Alex Pretti’s Sig handgun has history of accidentally firing – offering possible clue to why Border Patrol agent shot him | 25 Jan 2026 | Armed Minneapolis anti-ICE protester Alex Pretti was carrying a popular handgun that has a history of unintentionally firing — leading some gun experts to suggest that the gun might have accidentally discharged after a Border Patrol agent grabbed it from him, causing another agent to open fire, killing him Saturday. Pretti, 37, angry at President Trump’s crackdown on illegal immigration in Minnesota, was carrying a loaded Sig Sauer P320 9mm pistol when he allegedly tried to stop federal agents from arresting a woman on the street… Rob Doar, a lawyer for the Minnesota Gun Owners Caucus, said he believes that Pretti’s gun went off after the agent grabbed it, leading the other agent to open fire. “I believe it’s highly likely the first shot was a negligent discharge from the agent in the grey jacket after he removed the Sig P320 from Pretti’s holster while exiting the scene,” Doar said on X.
