While cleaning my 45 Tac tonight, I noticed one of my mags has the SA logo with "Croatia" stamped underneath. The other two are completely without markings. All 3 mags have identical baseplates, all are stamped "Springfield Armory" and "45ACP 13 rd". Just the mag bodies are different. All 3 are the mags that came in the box with the pistol. Wierd.
