The barrel is a KKM that Doc first checks out on a barrel tester to assure that it meets his accuracy standards. The barrel has a faster 1:32 twist so that it can properly stabilize the round nose 115 grain bullet. As received from KKM, the barrels are quite rough, so Doc precision laps them using a lathe. I’ve already run several hundred practice lead bullet loads (required on my indoor range), through my gun and there is absolutely no evidence of leading; the bore is mirror smooth. Doc threads the end of the barrel and fits an oversize stainless sleeve to the barrel, and then reams the slide opening for an exact fit to this sleeve. When in battery, there is zero play between the barrel & slide, and the frame, slide, and barrel are locked together like a bank vault.

I’ve been in the Bullseye game and a handgun collector for going on 26 years now, and I’ve either fired or closely inspected target pistols from most of the past and current master pistolmiths including Al Brian, Richard Shockey, John Giles, Bob Day, Jim Clark Sr., Mike Curtis, and Chuck Larson at Rock River Arms. Doc is definitely a player in this major league, and after understanding Doc’s innovations to the 92 platform, I think he just may be the “John Browning” of the Beretta 9mm.

To remove the play between the frame & slide, Doc uses a proprietary inletted rail system made of a special alloy. There is absolutely zero play between the slide and frame, yet the gun cycles very smoothly, even with reduced loads. Unlike the method of using inletted steel plates to accurize the 92, after extensive use, Doc’s rails can be replaced for a few bucks; restoring the original frame to slide fit.

Thank You
