The P series are short recoil–operated, locked breech semi-automatic pistols. They utilize a SIG P220 type locking system, and an M1911-style tilting barrel. The P series were made with a traditional double action/single action (DA/SA), or double action only (DAO) trigger mechanism. The early model P95's have fixed, three-dot sights; while newer P-95, P97 and P345 have three-dot sights adjustable for windage.
