The Browning 1911-22 is scaled at 85% of the full-size 1911, especially developed for 22 LR ammo with controls that operate just as those in the original Browning-designed Model 1911. Straight blowback action offers enhanced simplicity and reliability while a polished feed ramp offers reliable feeding with all types of rimfire ammo. The 4.25" stainless steel barrel of the 1911-22 A1 is target crowned and the aluminum frame is machined to exacting tolerances. Vertical serrations on the slide provide an improved cocking grip, and the manual slide release is easily operated with the shooting or support hand. It has a large manual thumb safety and grip safety. The 10-round steel magazine body is heat treated for long-term feeding reliability and long life with the magazine release positioned adjacent to the trigger guard for convenient operation. This model is CA compliant.
