ABOUT GLOCK

Even though the Gen4 improvements perform nicely on all the Glock body sizes, they definitely glow on the extremes, specifically, the biggest frame versions (G20 and G21) as well as smallest (Subcompacts). In the case with the weighty-hitting ten mm G20 and .45 ACP G21, the dual-spring recoil assembly properly lessens the level of felt recoil. Atta
