Since there seems to be little good information about this topic, I'll share information recently gleaned from posts on KTOG. It looks like magazines made for the Star S 380 and the Llama MicroMax 380 will fit *and* feed / work well in the P3AT. CDNNinvestments.com aparently had some 15-round mags for the Star before, but they are not advertising them now. They are, however, advertising 8-round mags for the Star. CDNN is also advertising 15-round mags for the Llama MicroMax 380, but the site lists that they are currently out of stock. I'm hoping they'll "find" some more or get in more stock, but I'm not holding my breath on this one. If anyone else has an opportunity to test other mfgr's mags I would appreciate it if the results could be posted. For what it's worth it appears that mags for the Colt Mustang, Mustang II & Gov't PocketLite may be compatible (just based on an examination of pictures of their mags, evaluating the placement of the catch hole & depth / width). Anyone ever tried Colt mags in a P3AT?
