It probably could, but it would be a lot cheaper to go buy a Bersa 380 for under $200. By the time a gunsmith figures out a way to change the trigger and associated hardware, then makes the parts from scratch, you'd probably be out about $500, maybe more. Sorry, but Colt designed it as a DAO, and there's not much left to do but shoot it DA or trade it off!
