Chip McCormick Power Mags Functional Power. Demand the highest levels of quality and function for long term reliability and service.
The CMcC magazines are my "go to" magazines when it comes to 45 acp. They always feed without a problem and always with a positive slide lock on empty. Most everybody raves about the Wilson Combat magazines, but these take the cake. And as always, Dawson Precision delivers.
Mag is made really well. I liked it but would not let the slide work properly on my STI Eagle.
Tested three mags today using Federal Premium 45 Auto, 185 grain FMJ Semi-Wadcutter, Gold Medal Match ammo. Had no feeding issues.
I did notice the follower seemed a little weak compared to my Dawson brand mags.
