I’ve never had a problem with Colt factory mags. The only problems I have ever had with 1911 mags were Springfield factory 10mm. Wilson Combat run that pistol just fine.
I'm new to the group, but not to 1911s. I got my first one 27 years ago. I've got 4 now. The best feeling, fitting, shooting gun ever created! I'm looking to add another one soon.
Carry on!
