I had a PA63 mag laying around that I had no use for as I had sold the gun some time ago. I decided to see if it would work in the P3AT. I matched up the level of the mag retention slot on the P3AT mag and cut a slot on the PA63 mag with a dremel. Not the cleanest cut but so what. The mag works great and holds seven rounds. I intend to see if I can cut the follower and or spring to get 8 rounds in it. It will be only for practice but it works and it didn't cost me anything. Regards, John
