So I bought an 8 round Sig Sauer mag for my Auto Ordinance 1911A1 (MAG-1911-45-8). The gun came with a 7 round mag. When I load up the 7 round mag it came with, rack the slide, drop the mag to reload another round, insert the mag into the frame so it is 7+1, and fire it, everything feeds like butter. When I fill up the 8 round sig, rack the slide, then fire it
it works fine. HOWEVER
When I load the 8 round sig with 8 rounds, rack the slide, drop the mag to load another round, pop the Sig mag in to make it an 8+1
jams on the 2nd or 3rd round. Any ideas?
