Introducing the new SIG SAUER Classic centerfire pistols in .22LR Rimfire models. The same Classic pistols that have been used by civilian, law enforcement, and military personnel the world over, can now have these same models factory built in .22LR. The SIG SAUER® Classic .22’s are built on the same frame as their centerfire counterparts. All Classic .22’s feature the same SIG SAUER Four-Point safety system which employs a decocking lever, a patented automatic firing pin safety block, a safety intercept notch, and a trigger bar disconector. The new machined slides also feature a front sight adjustable for drift and a rear sight adjustable for both windage and elevation.
