Got a NIB para gi expert .45 single stack today. Was checking mag function with snap caps and the slide wont hold open after mag is empty on most of the mags. The only mags that will are the wilson combats. The mags that don't work are new mecgars, chip mckormicks and even the factory para mags. Any ideas, is it a mag issue or a gun issue. I cannot see why new mags could be the problems
If you bought it new from a retailer I would just have it sent back to Para for warranty. There should be no good reason for it not to hold open with the factory mags if indeed it is NIB. From what I've heard they still have service in Canada but I could be wrong.
