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.
Modern, High-Quality with a fully heat-treated slide (to Rockwell-C hardness > 36)
Standard 5″, Normally Ramped, e. not fully ramped
Standard Barrel Bushing Configuration, e. no bull barrels
Not a “double-stack”….we have had very little success converting guns with 1911 DS magazines (see our FAQ “1911’s: Double Stack Magazines”).
For a list of some (definitely not ALL) potential models for an excellent Conversion, click on this link: https://www.460rowland.com/potential-1911-conversions/
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 https://www.460rowland.com/faq/
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 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.
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.
