1911’s: Basic Criteria for a Successful Conversion

We recommend many modern 1911-style pistols and have a few guidelines to help ensure you have a successful Conversion. We always suggest, if you are unsure, that you contact your gun’s manufacturer to confirm it meets our requirements, as below. This is particularly important with the heat treatment of the slide.
  1. Modern, High-Quality with a fully heat-treated slide (to Rockwell-C hardness > 36)
  2. Standard 5″, Normally Ramped, e. not fully ramped
  3. Standard Barrel Bushing Configuration, e. no bull barrels
  4. Not a “double-stack”….we have had very little success converting guns with 1911 DS magazines (see our FAQ “1911’s: Double Stack Magazines”).

If you love your 1911, you will really love what Johnny can do for it: True .44 Magnum Performance in a lightweight, high-capacity, easy to shoot, semi-automatic pistol. Enjoy twice the velocity and over three times the power of your standard .45 ACP.

Special Note re: Stainless Steel Guns

Stainless Steel has a higher coefficient of friction than carbon steel. The .460 Rowland® 1911 Conversion, when fitted to a stainless steel 1911 with a 20# Tougher Buffer Recoil System may not reliably eject low-powered .45 ACP ammunition.  That issue is readily addressed.
With the introduction of our Tougher Buffer Recoil System we now are able to offer a wide variety of flat-wound, dual-action spring tensions. These range from 13# to 24# and are for use with our Tougher Buffer’s .25” diameter two-piece, full length guide rod.
We recommend our Low-Rate Spring Tuning Pack for those looking for additional tuning options for their SS gun. We have found that one of these lower-tension, dual-action springs is often the remedy when the 20# spring struggles with .45 ACP.
Polishing your rails can be helpful as well. This is a relatively simple task. See our FAQ #56
All 1911’s are a bit different and in some rare instances the higher friction of the stainless steel will prevent you from shooting both .460 Rowland® and .45 ACP from the same set-up. Should that happen with your gun you may need to revert to your stock barrel and recoil spring assembly to reliably cycle .45 ACP ammunition.
And of course, if you need any help or advice along the way, we are always here to help in person in Tulsa, via email or over the phone (918) 928-7460. We have successfully converted hundreds of SS guns….yours can be the next!

About the .460 Rowland® 1911 Extended Firing Pin

If you are experiencing primer blow-by it may be because you have an old-style .45 ACP firing pin assembly. Upgrade to our .460 Rowland® Extended Firing Pin to remedy these issues.
Some 1911’s (even some very expensive models) have stubbornly adhered to John Browning’s original design and not gone to this more desirable firing pin assembly.
The .460 Rowland® 1911 Extended Firing Pin solves the blow-by problem and has proven to be preferable when shooting some of the more modern high-pressure cartridges like the 10 mm, .45 Super and the Big Dog, the Mighty .460 Rowland®.
Longer, Thinner and Stronger to resolve primer blow-by problems in your:
  • 1911 5″ “Gov’t”
  • 1911 Cobra
  • 1911 4.25″ “Commander”
 It includes an Extra Power Firing Pin Spring. Compatible with your large or small diameter .45 ACP firing pin assembly.
 Firing Pin Diameter: .067″

The “Permanently Attach” Option:

The purpose of this Option is to permanently secure the Compensator to the barrel to make it legal in California and other restrictive states. With the exception of the 1911, the customer must send their slide to 460 Rowland LLC for securing.
For the 1911, the barrel is removable/replaceable even after the Compensator is attached, so only the barrel need be sent. In the case of a new Conversion sale, we can secure the Compensator before shipping your order.

The .460 Rowland® Tougher Buffer Recoil System

 The .460 Rowland® Tougher Buffer Recoil System was originally designed as an integral part of our .460 Rowland® Cobra Conversion.  Now included on all .460 Rowland® 1911 Conversions, it is also available as a stand-alone assembly to enhance the performance of your existing 1911 Conversion or your stock 1911 .45 ACP (or 10mm) handgun.
This Dual-Action innovation effectively reduces felt recoil while saving your frame from undue punishment in a smooth and sustainable way.


What makes the .460 Rowland® Tougher Buffer Recoil System such an Improvement Over the Standard, 200 Year-Old Design?

  To begin, this Dual-Action, Flat-Wound Recoil Spring System stacks in a smaller space, lasts longer and runs smoother than assemblies with conventionally-wound springs.
  • By nesting a short section of flat-wound spring inside the base of the main spring, we permit the gun to unlock and begin its cycle under normal spring tension.
  • As the slide accelerates and approaches the end of its cycle that inertia is resisted gradually by the second spring until, finally, twice the starting spring tension is being exerted against that moving hunk of steel.
  • This Dual-Actioninnovation effectively reduces felt recoil while saving your frame from undue punishment in a smooth and sustainable way.

Tuning Options:

  • Our complete  Tougher Buffer Recoil System includes our full-length, two-piece Tougher Buffer Guide Rod mounted with our 20(40)  Dual-Action Recoil Spring .
  • Because every 1911 and every shooter is different, we offer a wide range of tuning options with compatible flat-wound Dual-Action Recoil Spring s , either individually orin Tuning Packs:
o    24 (48) lb.
o    22 (44) lb.
o    20 (40) lb.
o   17 (34) lb.
o   15 (30) lb.
o   13 (26) lb.
o   High-Rate Tuning Pack: includes 24 (48) lb.  and  22 (44) lb Dual-Action Recoil Spring s
o   Low-Rate Tuning Pack: includes 17 (34) lb., 15 (30) lb. and 13 (26) lb. Dual-Action Recoil Spring s (recommended for SS guns)
The Tougher Buffer Guide Rod is also available separately.

A Word About “Recoil Buffers”:

 Why not just use the plastic or teflon Shock/Recoil Buffer Rings sold for use between the end of your guide rod and slide?  Well, these little cushions do nothing until the slide gets up a full head of steam. Imagine trying to reduce or buffer all that energy in such a very short distance, i.e. the thickness of the buffer ring.  They are much less effective, take a terrible beating, come apart quickly inside your gun and must be monitored and replaced before they cause misfires.
In designing the iconic 1911, the venerable John Browning deliberately used the metallic “ping” at the end of each cycle to shake up the stack of cartridges in the magazine (keeping them fluid) to facilitate more reliable feeding.  Recoil buffers dampen that all-important “ping”. They are not very effective and can lead to potential misfires from failure and jamming.  Johnny says:  “Just Don’t Use Them!”
The .460 Rowland® Tougher Buffer System   is elegant, versatile, lasts longer, will never break down in your gun and is simply more effective than other recoil assemblies available.
About our Tougher Buffer Guide Rod:
Full-length guide rods are generally considered better because they force the recoil spring to stack without kinking or twisting and we agree.  Our Tougher Buffer Guide Rod is .25″ in diameter (thinner than most) to accommodate the flat-wound springs we like so much. And now it is fluted , making it easier to take apart i the field without an allen wrench.


 A Final Word:

 We stand behind our products “®”.  Try them and love them…or return them for repair, replacement or refund.

  2. Subject: Conversion kit

    Message Body: Im just posting this to tell you guys how much I enjoy my conversion kit. It was harder to install than I thought due to the 20 lb. dual coil spring, but that well makes up it in the accuracy and performance I now get out of my 1911.

    — This e-mail was sent from a contact form on the website.

  3. I have a 44 mag 1911. I found 460 Rowland I can do faster follow up shots. And I can defend my neighbors house from mine. I really like the variety of ammo. I had a pair of Kimbers converted. I can still shoot 45’s also. I live in bear country. Camp alot.

  4. I love the fact that I get 44 magnum power with less perceived recoil, much less muzzle blast and faster follow up shots than the 44 magnum. And all with a common .45 cal bullet and in an extremely accurate 1911 action.

  5. Subject: Thank You!!!

    Message Body: Just received my new compensator. You folks are absolutely the best. 2 days after the order!!! I l love your products. My wife bought me a brand new SOCOM model Kimber Warrior for the express purpose of converting it to .460 Rowland. I will be ordering a complete kit next pay day. I have never had so much fun as shooting my Glock 21 with the .460 installed. last year I took a big male Florida boar hog at 75 yards with the Glock braced on a truck bed at 75 yards. Bullet went clean through destroying the heart. He was down without a grunt. My companions could not believe what they just saw. An hour before they were scolding me for daring to hunt with a Glock 21. I wish there was some way to pu the .460 in a Glock 41. I have a Glock model 40 10mm and I love it but something that size in .460 Rowland would be a dream. Thanks.

  6. Thomas. Just wanted to show you the final product. Had the barrel hard fitted into my EDC Colt Custom Tactical. I have shot 200 rounds of Underwood .460 through it both 255 hard cast flat nose and 185 JHP. Definitely gets your attention. No FTFs and great accuracy. Thanks again for your help!

  7. Thanks to everyone at 460 Rowland. Got my kimber raptor II back. Performs flawlessly!! I got a second kit and did my kimber aegis. Wow what a difference. I was in the military over 20 years and retired. Had we had the 460 Rowland. I’d have stayed longer.

    When I mentioned to Thomas about my military service. He recommended shipping my 1911 in for the conversion since it’s stainless. I was blown away by him doing labor on upgrade free. What an amazing weapon!!! My wife and I camp allot. I live in bear country and have them in my dumpster on occasion. I’d only shoot as a last resort. But I do know the 460 will do the job if needed.

    Again. Thanks to everyone at 460 Rowland. You will get my business always.

  8. Best conversion on the market. I only recommend using authentic 460 Rowland. Love both of mine.

  9. Just wanted to take a minute to thank you for the help in building my new 460. Had a question or two and was given great service when I called. First time out to the range I put 300 rounds of light powered 45 acp. No failures other than when a friend was limp wristing when he was shooting. Light loads will tend to do that with a heavy spring installed. Only complaint I might have is not offering a stainless guide rod set in place of the blued for those who purchase a stainless set. As for accuracy I have to admit this may be the most accurate 1911 I have ever shot. Routinely, even with light ball ammo, I can produce one hole at 45 feet in a range setting. Thanks again. And I left a few pictures to show you the build.

  10. I could fix my comp but I would have more peace of mind if I sent it back to you guys. I will get a USPS box this evening and get it in the mail tomorrow. I really appreciate you taking care of it for me!! I can’t express how impressed I am with the conversion. In the 20rds I did fire I had NO FTF or FTE!! I only took 1 box of Ammo with me to range which is 45min from my house or I would have shot ALL my ammo last Friday……lol!!! A gentleman had a Ruger Super RedHawk 44mag at range & he was kind enough to let me compare recoil to mine….. NOT even close!!!! Lol!! My 1911 shoots smooth as butter with the 460!! Ruger had 8 3/8 barrel, I STILL shot BETTER groups at 50yds with MINE!! Lol!! Ooh yea, he LIKED my conversion , also!!! Well I could go on & on but I guess I better get my barrel ready to ship back….MISS it already!!! LOL!!! Thanks again , Dave you have been GREAT!!!

  11. Thomas,

    I went shooting the .460 Rowland today. I shot about 150 rounds, to include all of your three types of ammo, and everything else that I’ve loaded up. The pistol functioned flawlessly, and it’s quite accurate to boot. The new firing pin made a great difference, no more torn up primers. You do great work!

    Thanks again

  12. (verified owner)

    I caught the 1911 compensated kit on sale and wow! The kit is easy to install and the fit/finish/quality of the kit is outstanding! I would definitely recommend and have recommended this kit to anyone that will stand still long enough to listen! And for a bonus, you retain the ability to fire 45 ACP, so it’s a “no-brainer” for me to convert any future 45 that I purchase!

  13. Dave, Thomas, Cindy –

    I just wanted to take a minute and update you on my recently converted Ruger SR1911.

    First off, I want to say what a pleasure it was to work with you all on getting what turned out to be a sort of project completed and ready to shoot (and kill bears and cougars, should the need arise). My customer service experience was nothing short of stellar – the personal phone calls, emails, and the overall customer / provider relationship 460Rowland provides should be a model for all businesses in the firearm industry. That’s because of the deeply felt attachment that most gun owners have for their guns. Therefore, to trust someone with what most of us call our “babies” is a big deal – 460Rowland is, without question, worthy of that trust.

    Second, the gun itself is beautiful. The fit and finish is perfect, tight, and clean. This was more of a custom job because of the fit issues we had between the stainless steel and the conversion kit, but the smithing was done well. There is a sense of doom looking at the engraved “Authentic 460 Rowland” in red on the front of the compensator. Love it!

    Third, the shootability. I’ll begin by saying that I put 4 full mags of “Johnny’s Personal Carry” 185 grain (35 rounds) through the gun without a failure to eject, a failure to feed, or any other loading or firing issues….There is a massive amount of power in this gun! The term “beast” more than aptly applies here, and I’m not exaggerating. The awesome thing is that all that power (all 44 magnum’s worth of power, to be precise) is handled with relative ease. In fact, for me, the gun handles better as a compensated .460 than it does as a non-compensated .45 ACP. The top-vented compensator keeps muzzle-flip to a minimum (and I do mean MINIMUM), while the recoil seems to come down the forearm.

    I’m not kidding when I say this: I literally felt the recoil come out of my elbow instead of the top of my wrist and forearm. That’s a big deal to me since I was able to keep all shots on target with half the re-aim time. At 15 yards I let out an entire magazine in just a few seconds (as fast as I could pull the trigger) and every round hit my target-zombie’s torso – in the kill-zone! Not a tiny grouping, mind you, but very impressive, and something I couldn’t do as well with a standard 5″ .45 ACP 1911. I’m just not as good as others.

    Speaking of accuracy, this is nothing short of amazing. Taking more time to aim, I destroyed a small 8″ diameter balloon (I know, not that exciting, I wish it had been an exploding target) with a single shot at 55 yards. That tells me that the gun is perfectly balanced, the ammo does it’s job of flying as perfectly and flatly as scientifically possible, and the conversion kit is machined with unsurpassed precision. There are a lot of better shooters out there than me, most, actually, but I still feel like that is a sign of the guns worth. My 460 feels more of an extension of my arm than anything else I own, and, again, that is no exaggeration.

    Breaking down the gun is easy. Not tool-less, but easy. After shooting (I only put 35 rounds through since….I wanted to make sure I had some left to keep in the mag until I ordered more), anyway, after shooting, I broke “the she-beast” down, cleaned her with hot soapy water, lubed each part as I put her together, cycled a couple unfired mags through (not a good habit, I know) just to make sure, and, again, flawless. She’s now hanging beautifully from her hangar in my safe, cleaned, slicked up, and ready to go hunting with me in a couple weeks.

    I’ll end this long email by saying I have recommended 460Rowland to all my friends, and everyone else I talk to about guns. I will absolutely do business with you all again – I intend to build another, but this time blued instead of stainless. There’s just something exciting about the thought of having one in each finish. You’re a great company with an incredible product, unmatched in my opinion. Thank you again for all your help. You’ll be hearing from me again soon.

    With all sincerity,


  14. Hello,

    It was a pleasure to speak with you last week and I am looking forward to the kit for my Springfield 1911. Before I receive the product I can tell that I am dealing with a level of experience and professionalism that is rare today. I wanted to thank you for spending the time to field my questions and make suggestions regarding the functionality of the new kit.

    Thank you George B

  15. Customer Email from Mark P – May 19, 2017:

    We own a gun shop and I am a gunsmith in No. Wyoming. We have a ton of grizzlies and wolf…Outdoorsmen always want a hi-cap auto for protection in grizzly country. The 10mm is not a grizzly round though there are retailers who praise the 9mm for big bear with a 17 rd. capacity. NOT TRUE, you’re not going to get 17 shots off at a charging bear at 10 yards!!
    I am also a guide, have hunted Alaska for brown bear and believe me I know what those bear are capable of and what it takes to stop one….Bears are just poking out now…I’m interested in .460 Rowland® for me and my two sons as well!

  16. Hello Dave,

    I received my kit yesterday for my 1911. I greatly appreciate you sending me the kit in a timely manner, your customer service is awesome! Your communication was great- thank you for telling me about the guide rod, and spring plug not being blued- that would have been a surprise. I assembled the kit in the gun and the fit is great, the alignment of the compensator is perfect as well. I removed that red dot that covered the “pin and weld” and covered the hole with black high temp paint (I figured it looked batter than the red dot). I gotta say this is a real sweet shooter! It cycled .45acp perfectly and dropped the brass about 3 feet away. When shooting the Mighty .460 Rowland cartridge the gun was very accurate and the brass flew about 10+ feet away. It cycled perfectly with whatever I put into it. I did have a few primer strikes where the primers blew threw- is the extended firing pin what I need to remedy this? I am very pleased with the results of this cartridge.

    I will be purchasing ammo and a T-shirt shortly for a YouTube .460 kit, and ballistics/chrono test…..I greatly appreciate your customer service and help. I have had a good experience with this company and want everyone to know about it.

  17. I converted a Glock 21 about a year ago and liked it so much I wanted to convert another. I ended up going a different route and went with a Kimber 1911. Its a sweet shooter. I have another Glock 21 sitting in the safe waiting to be converted, and have 500 new casings waiting to be loaded.

    Its a shame that more people don’t catch on. It is a reloader’s dream and the published ballistic numbers don’t lie. I load 230gr Hornady XTPs to 1330 fps, which is touching 44 mag territory. The Glock 21 holds 14 rounds, the Kimber 9, and a 44 mag six. The G21 is about a lb lighter than a typical 44 mag.


  18. Hi Cindy, I just wanted to let you know that I received the firing pin in the mail yesterday. I want to tell you that dealing with you guys has been a great and easy experience and I will recommend you to my son’s who all have 1911’s as well. Thanks and God bless your business!

  19. I just took my new 460 Rowland out to the range today and I am very happy.

    It fed my boxed 45 and 45 +p defensive loads flawlessly. Your 460 Rowland worked fantastic through factory mags and an old colt mag. My Wilson Combat mags had occasional problems with the 460 only.

    My local store did not have any chip mags as you suggested but I will order some as I would like a couple of 100 percent reliable 8 round mags for 460. My Wilson mags will be consigned to 45 acp only.

    Thanks again you have a new loyal customer.

  20. I just wanted to drop a line to tell you how much I enjoy my 1911 Conversion. I have put 3000 rounds through this gun and it seems to get better with age. Does everything you advertised. Bravo

  21. Subject: Stainless Remington R1

    Message Body: I bought a conversion kit for my R1 SS 1911 last year, been tinkering, and had a beaver tail safety, sear, and hammer fitted. WOW! Said might have to lap rails. Not necessary on mine. Ejects 45 ACP about 1 or 2 feet, 460 shells go about 20. Turned a boring factory second 1911 I bought while working at the Remington ammo plant into something really exciting and comfortable to shoot. Many thanks.

  22. Hello Dave (and before hand Cindy),
    I just wanted to thank you guys for the excellent service I have received in the last 24 hrs. Best service I have experienced (especially since I work night shift). Instead of just cancelling my order, like most other purchases I have tried making when something minor was wrong. You guys there worked to see my order go through. I am pleased and it shows me that you guys at 460 Rowland are not just trying to make a profit, but really want to get your product out there and to satisfy your customers. Once again a big thanks.
