Introducing the “Dave Saye Ported .460 Rowland® Barrel”: Our newest Ported barrel design is Inspired by one of the area’s best gunsmiths, Dave Saye, of L & L Machine Guns and MacKools Firearms, in Tulsa Oklahoma. Dave enjoys his Glock-21 in .460 Rowland® and designed his own, very effective, compensator to dissipate spent gas laterally through a 365 deg. pattern of circular ports. Although we have not fully incorporated Dave’s design in our compensated conversions, we have added a few lateral ports to very good effect. Our Ported barrels, however, have been dramatically improved by the new design. The radiating three row pattern of circular ports found in our new .460 Rowland® Ported Barrel Conversions do a wonderful job of reducing slide speed and felt recoil … we love shooting them! We highly recommend Mr. David Saye, L & L Machine Guns and MacKools Firearms for all your general gunsmith and Machine Gun needs. Ask around and you’ll find that we’re not alone.
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 light-weigh, 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 Glock-21 is rugged, reliable and easy to shoot. It runs like an appliance and is a wonderful platform for the Mighty .460 Rowland®. Everything you need is included in the Conversion price, including the awesome rapid-target acquisition Rowlanator® rear-sight replacement.
Simply replace your old barrel with our new Ported .460 Rowland® Barrel. Install the included 24 lb. flat-wound stainless steel recoil spring assembly and the Rowlanator weighted rear-sight replacement to build the most reliable, most powerful and highest capacity handgun legal to carry in most states!
The .460 Rowland® barrel porting system was developed to conform to California’s strict prohibition against “assault weapons”. The fully compensated conversion does do a better job of reducing recoil, muzzle flip and flash; however, the ported conversion has the incidental advantage of being completely removable without having to detach a screw-on-compensator.
