Compact defensive pistols that balance concealability, shootability, and stopping power are rare. For shooters seeking an easily carried .45 without the bulk of full-size pistols, a purpose-built compact offers an attractive middle ground — lightweight for everyday carry while retaining the ballistic advantages of .45 caliber performance.

Design and build

The KAHR ARMS P45 is best described as an incredibly lightweight .45 caliber pistol featuring a textured black polymer frame paired with a matte blackened finished stainless steel slide. The polymer frame incorporates steel inserts that engage the slide rails — a deliberate design that preserves long-term durability and consistent slide-to-frame fit for enhanced reliability and accuracy.

Frame, slide and finish

The KP4544 matte stainless slide is blackened with an ultra hard, super thin coating borrowed from knife-industry proven treatments. That coating reduces corrosion and resists scratches while keeping slide mass optimized for the P45’s compact footprint.

Barrel, rifling and ballistic considerations

3.5-inch barrel with polygonal rifling

The 3.5-inch barrel features 1-in-16-inch polygonal rifling. Polygonal rifling can yield slightly improved velocity and easier maintenance compared with conventional land-and-groove rifling, while the 3.5-inch length balances muzzle energy and concealability for defensive loads in .45 caliber.

Handling, dimensions and intended use

At just over six inches overall and 4.55 inches tall, the P45 literally fits in the palm of an average hand while providing enough grip surface to index the hand comfortably. The textured polymer grip aids retention in adverse conditions, and the reduced weight makes it suitable for daily carry without sacrificing the terminal performance of .45 caliber rounds.

Priced at $418.99, the P45 is positioned as a value-oriented compact semi-auto for shooters who want .45 performance in a modern, lightweight package. View product details and pricing on our site to compare options and accessories.
