The Beretta 92 is accurate. This 92F is box stock save for LPA sights just attached by Bill Pfeil. Five shots from 25 yards and five from 50, hand-held from right-hand barricade position, resulted in this 10-shot group of less than 3 inches with inexpensive Federal American Eagle ball.
In the shape of the barrel and slide, and to some degree the overall shape of the gun, the Model 34 presaged the Model 92. But other major design elements were drawn from elsewhere.
The locking block design of the Walther P-38 pistol in 9mm Luger, adopted in 1938 by German armed forces as their primary service pistol, would also find its way into the Model 92. Gun expert Charles M. Heard explained, “The P-38 fires 9mm Parabellum rounds handled by a short recoil system with the barrel being disengaged by cams which are movable inclined planes.” (2)
The Walther P-38 also featured a mechanism in which the initial pull of the trigger, “double-action,” first raised and then dropped the exposed hammer to fire the chambered cartridge. As the gun cycled, the slide cocked the hammer, and subsequent shots would be fired with the easy single-action trigger pull. The hammer would be lowered by an internal decocking mechanism, activated by pushing down a lever on the left side of the slide, which when in the down position also functioned as a manual safety catch. This in turn derived from an earlier Walther, the PP/PPK series of pocket-size pistols in .22 LR, 7.65mm, and .380. These pistols had debuted in 1928. While Czech pistols had been built around the double-action feature earlier than that, they had been double-action only, even after the first shot. Walther was the first to produce a double-action mechanism that functioned only on the first shot, cocking itself to single-action for follow-up rounds. Smith & Wesson would adopt it before it was adopted by Beretta, but this Walther concept would find its way to the Model 92 as surely as the P-38 lock-up design.
