The P40 offers a unique rotating barrel mechanism to those who prefer shooting with powerful .40S&W / 10mm AUTO / .357 Sig rounds. Built on the latest generation of Mk12 polyamide handle, but it features a new steel dismantling catch which replaced the original trigger guard stop. This innovation results in a stronger handle, enhanced reliability and easier field stripping. The new rounded slide profile provides excellent handling and ergonomics. Longer L model provides even more accurate shooting and increased mass shifts center of gravity towards muzzle to further reduce muzzle lift.
