Armscor - ACT-MAG Sig P220 8 RD .45 ACP blued P220B-45-8, 44522
[Armscor / ACT-MAG 44522]

Great mags, have put several hundred rounds through them, honestly I cannot tell them apart from the Sig Sauer OEM mags that came with my new 2011 Sig P220. On closer inspection, the mag well, spring and the floor plate are IDENTICAL, both say made in Italy! There is only a slight difference between the Sig and ACT-MAG follower. There is a small metal insert on the follower that the Act-Mag doesn't have, but has zero effect on its function. Buy em, I recommend the nickel plated ones too for a few dollars more, they look nice and are easy to clean.
