Description

The Glock-21 is rugged, reliable and easy to shoot. It runs like an appliance and is a wonderful platform for the Mighty .460 Rowland®. Simply replace your Glock-21 barrel and recoil spring assembly with your Authentic .460 Rowland® upgrades and build the most reliable, most powerful, highest capacity, handgun legal to carry in most states!

Our “Unique and Proprietary” products are “Often Copied but Never Duplicated”, so don’t be fooled by “fraud”. Look for our “Federal Trademark” Insignia, (“®”), to be sure.

With thirteen .460 Rowland® cartridges in the magazine and one more in the chamber, you’ll be packing over 14,000 foot-pounds of bone crushing, grizzly-stopping energy that you can accurately and rapidly place farther down range than ever before!

This lightweight, reliable system delivers true .44 Magnum performance with much less recoil, noise, muzzle rise, and night-blinding flash than the legendary .44 Magnum alternative.


The “Pin and Weld” Option :
The purpose of the Pin and Weld 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® for pinning.

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 pin the Compensator before shipping your order.

 

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

    I own this kit. The kit was easy to do. On top the round has some massive power. I shot at 25 feet and hit the target in the same spot each time. The round is powerful and is something that you dont see in a normal gun or round! I have shot some big caliber guns before but this is something to have. I enjoyed it a lot. The best part you can change the guide rod back to a stock glock 21 guide rod and be able to shoot standard 45 acp rounds throuhg it.

  2. Comment:
    Hey guys, when I was thinking about getting one of these conversions I was looking to see what other guys had to say about it. Well not much here. So let me tell you what I think. I took it to the indoor range and the first time I pulled the trigger I giggled the second round I had an audience. I’m telling you straight up it is a true hand cannon. I had got lucky and the guys at Rowland were able to hold my order and send some of the 240gr magnum rounds with the conversion. They have a hard time keeping them in stock. They have this huge fireball that comes out with a huge kick. Sooo cool…. I have the Glock 21 full size. 45 and even shooting the +P rounds the Rowland as twice the the bang. Lol that’s the s**t I paid for, so if you are considering one of these and are not sure about it I will say it far exceeded my expectations. I did get the upgraded mag Springs and didn’t have any malfunction. I only shot 50rds, but that’s all I needed from this beast. You should get one so you can rattle your range it’s so funny when everyone is asking wtf is that guy shooting down there.

    Message Body: Hello, Just wanted to say how satisfied I am with the 460 Roland kit I installed on my Glock.The installation was very easy,and the instructions were clear,and precise,as you know I also ordered the heavier springs for my magazines,and after watching a youtube video I installed the springs,plus I also installed the shims to the sides of my 460 Roland magazines. Once the lock tight has completely setup I will be off to the range,and will give an update as to the performance of this entire 460 Roland modification….Thank you for your help,and advise,and the fast shipping…C.J.

  4. 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!

  5. I was hunting about 3 weeks ago here in Montana and took a 150 lb black bear with a 460 Rowland. Sorry my Glock 21 conversion is not in the picture. I love the set up, its almost a lb lighter than the 44 mags I have, and I got double the capacity. It is also very accurate for a pistol. I think I am going to build a second G21 460 Rowland here soon.

    Thanks,
    Chad S

  6. 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.

  7. Message Body: This weekend was my first opportunity to shoot my Glock converted to the 460 Rowland. I started out with the Glock 20 so I had to buy a Glock 21 slide to work with your kit. All I can say, is this is amazing. I found the recoil of the 460 Rowland to be more agreeable than the 10 mm. My new favorite.
