The USMC will be replacing their nylon pistol holsters for Blackhawk’s polymer SERPA Level 2 Tactical Holster. The holster is controversial because if not careful, a shooter can hook their finger in the trigger when drawing it and discharge the gun into their leg.

In an emailed response to Marine Corps Times’ questions, officials at MARCORSYSCOM said the holster was put through rigorous safety tests in July by Marines assigned to Quantico’s Weapons Training Battalion. After giving the holster to Marines of varied pistol-shooting abilities, from expert to novice, Weapons Training Battalion concluded the SERPA holster is safe for issue, according to MARCORSYSCOM.
“We did not see a trigger-hooking problem,” officials said. “We found the SERPA design allowed natural positioning of the trigger finger during the draw so that it was straight and off the trigger when drawn. … Weapons Training Battalion, our premier weapons trainers, oversaw the evaluation of the holsters and no safety concerns were identified by the users or the observers of the evaluation.”
