A Pennsylvania-based U.S. Immigration and Customs Enforcement agent and former Marine has launched a defective design and breach of warranty lawsuit against the manufacturer of a striker-fired, semi-automatic pistol that, according to the suit, shot the agent through the leg without him ever touching the trigger.

The action lodged Wednesday in Philadelphia federal court by Keith Slatowski, an ICE deportation officer with 12 years of experience, alleges that the New Hampshire-based gun designer and manufacturer defendant, Sig Sauer, has faced numerous lawsuits nationwide over the allegedly defective design of its P320 semi-automatic service handgun, which was the government-issued weapon that Slatowski says fired on him last September as he did training rounds with it at U.S. Postal Service range in New Castle, Delaware.
