THE 2-MINUTE RULE FOR INC.

Even though the Gen4 changes operate nicely on each of the Glock frame measurements, they actually glow for the extremes, namely, the largest frame designs (G20 and G21) and also the smallest (Subcompacts). In the case with the weighty-hitting ten mm G20 and .45 ACP G21, the dual-spring recoil assembly properly decreases the extent of felt recoil.
