Kahr Arms, a a Worcester, MA-based manufacturer of compact pistols, is currently engaged in a patent infringement lawsuit against Diamondback Firearms, LLC, the maker of compact .380 ACP and 9mm pistols based in Cocoa, FL.


According to a press release, seven U.S. patents cover Kahr's unique locking, firing and extraction systems. The incomparable cocking cam trigger system employs a patented cam to both unlock the passive safety and complete cocking and releasing of the firing pin. The system provides a “safe cam action” and unbelievably smooth double action only trigger stroke, fast to fire in critical defensive situations.

Kahr said the design is original, creating the smallest package possible in four defensive calibers – 9mm, .40S&W, .45 ACP and the .380 ACP.


Representatives for Kahr said that in recent years, the market segment for compact pistols has attracted the attention of a number of large and small companies vying to gain market share as the larger pistol market has slowed down.
