Kahr Arms PM45 | .45 ACP | 3.24 Barrel | 5+1

The Kahr PM45 is a compact, single-stack pistol chambered in .45 ACP designed for discreet carry and accurate short-range shooting. It features a textured polymer frame paired with a matte blackened stainless steel slide and drift-adjustable tritium night sights for reliable sighting in low light. The PM45 uses a trigger-cocking double-action-only system and a polygonal-rifled barrel noted for consistent performance. A cost-effective optic that pairs well for slide-cut or mounted solutions is the Holosun 507C, which offers a compact footprint and optics performance under $1,000.

Applications: everyday carry (EDC) and range/training are two primary uses well-suited to this model.
