The PM40 is built on a black polymer frame reinforced with steel slide-rail inserts for durability and smooth cycling. Its matte stainless slide features rear serrations for positive manipulation, and the overall package remains extremely slim with a 0.94 in slide width.
The 3.1 in barrel uses polygonal rifling with a 1:16 RH twist. Kahr's offset feed-ramp and low-bore-axis design are central to this model's engineering, aiding controllability and reliable feeding in a compact format.
Sights are Kahr's white bar-dot setup: a white dot front paired with a drift-adjustable rear featuring a vertical white bar. The trigger system is double-action-only with a striker-fired, short-recoil, locked-breech action, consistent with the PM Series design.
This pistol is part of the PM Series and is marked Worcester, MA. It has a 6+1 maximum capacity and ships with both a 6-round and a 5-round magazine. Documentation includes a factory test-fire envelope dated 09/25/2006. The case label reflects SKU family PM4043 with specific part number PM4043A.
