While it bears a strong family resemblance to the P45 and uses the same textured polymer frame (Kahr pistols have a snag-free exterior, a nice feature for a pistol meant to be carried and drawn from concealment) the Kahr CW45 is intended as an entry-level or economy model. It's priced at $200 less than the P series .45s.
The polymer grip frame is nicely checkered and textured to provide a non-slip purchase. The CW45's slide stop is produced by a metal-injection-molding process; on the P series it's a machined part. The barrel on the CW45 has conventional rifling, as opposed to the P series' polygonal rifling.
