Gunsmith Fit 5″ 1911 / .460 Rowland® Conversion


For $310.00 you will receive the following:

– A threaded stainless steel barrel that is chambered in .460 Rowland. (#4 link and pin installed)
NOTE: This barrel is designed for a standard 5″ 1911 platform. Fitting will more than likley be needed to install this barrel into your host gun.
– A case-hardened, black compensator with red paint-filled engraving
– An upgraded, thick barrel bushing
– A 460 Rowland Barrel Bushing Wrench
– A heavy 24# 1911 recoil spring

This barrel is designed for a standard 5″ 1911 platform and will need to be fit to your host gun.

Don’t want to do the fitting? Not a problem! For and addtional $150 we will accept delivery of your complete firearm, fit the barrel to your firearm, range test it and send it back to an FFL of your choice. Just make sure to select this option before placing the product in your cart.

This 24# spring will more than likely be too stiff to cycle your regular .45 ACP but will allow you (in conjunction with our compensator) to safely cycle .460 Rowland

If you want to cycle .45 ACP, 45+P and the Mighty .460 Rowland® reliably, [without removing your compensator or changing your reaction spring, or both], we recommend you upgrade to one of our Upgraded Recoil Assemblies. Either our time tested .460 Rowland® Tougher-Buffer, or our space-age V2-Recoil-Damper.

The 460 Rowland V2 Recoil Damper is a precision-machined “micro-motor” designed to manage slide speed and recoil. It consists of a piston and cylinder coupled with our 30-50,000 cycle reaction spring. It actively slows the slide, regardless of force, in the last inch and a half of travel.

DISCLAIMER: All our 1911 kits use standard un-ramped barrels and barrel bushings. If you need a fully ramped barrel, bull barrel or any specific combination please contact us for pricing and availability. For best results we only recommend using single-stack 1911’s.

This specific product will need to be fit to your gun. 

About the Tougher Buffer

The Tougher Buffer Recoil System consists of a two-piece full-length guide rod, an open-ended guide rod plug, a full length, flat-wound, primary reaction spring; and a short, secondary, flat wound spring. This great, time tested, and economical system lasts longer and is more effective than other recoil assemblies on the market.

The full-length guide rod keeps your springs straight and creates smoother and more reliable operationm and allows the operator to assemble the gun more easily than if he or she were using a single-piece, full-length guide rod. The flat-wound springs makes room for more coils per inch and is what allows us to add that all-important secondary spring.

The Tougher-Buffer’s long primary spring is selected to let the first half of your 1911’s cycle to proceed under a comparatively low tension, making installation and operation easier and more reliable.
The secondary spring, being wound into the base of the primary spring, allows the Tougher Buffer Recoil Assembly to present twice as much recoil dampening force in the last inch of travel to your slide when it slams to the rear.  20lbs, for example, becomes 40lbs, 18lbs becomes 36lbs … and so on.  Your gun will operate and rack easily on the one hand, and will more gently and reliably eject your spent brass on the other.

A 40lb spring, for example, would be extremely difficult to install and manipulate before firing, and would markedly reduce the reliability of your 1911.  This ingenious Tougher-Buffer design gives you the best of both worlds, more recoil spring tension when you need it and less spring tension when you don’t.


If you’ve been disappointed by other recoil systems we have a solution for you.

If you’re ready to upgrade your handgun to a truly superior recoil system that will not break or fail, the 460 ROWLAND® V2 RECOIL DAMPER is the upgrade for you. This device really works, folks.

The 460 Rowland V2 Recoil Damper is a precision-machined “micro-motor” designed to manage slide speed and recoil. It consists of a piston and cylinder coupled with our 30-50,000 cycle reaction spring. It actively slows the slide, regardless of force, in the last inch and a half of travel, working much like the air brakes on a semi truck.

With that force absorbed, the reaction spring now has only to return the slide. This enables you to use whatever tension you like that will return it to battery: Higher for a rugged backwoods environment, very light for competition shooting…or anything in-between.

This was John Browning’s original

intent for the spring. It is now realized again with today’s more powerful rounds. And the V2 Recoil Damper will work with any caliber.

The V2 Recoil Damper includes a Standard Reaction Spring and a set of six SS Shims.

Different Reaction Spring tensions and additional Shims, including more elegant Brass Shims, are available to suit your needs.

Special Note: Stainless Steel Guns

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, additional tuning may be needed. This is a relatively simple task. 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 Stainless Steel guns….yours can be the next!

If you’d rather have us do the install, tuning and testing, you can always ship us your entire gun for conversion!

  • When ready for the re-assembly, clean the threads thoroughly before applying your blue thread-locker. This is best done with clear alcohol or lacquer thinner and a wire brush or steel wool.

(Acetone leaves a residue and is not recommended.)

  • Apply a small bead of BLUE thread-locker to the end of the barrel and set-screw threads. Be prepared to proceed directly to the

next step of these instructions.

  • With your .460 Rowland® barrel in your slide screw the Compensator onto the barrel until it is close to the slide, but not actually touching Likewise, do not tighten the Compensator all
