Some people love the Tapco mags. I has crapcos when they first started making them. Some were 1/8 too thick to fit in a magwell, they also had follower issues.
Hard to tell, 3 different ones wouldn't fit in magwells, shaved one of them down to fit and the follower hung up. They're only $3.99, buy a couple and test em....

I've used approx. 10,000 rounds of the Aguila Super Colibri, while I KNOW this is a MUCH different round, I would estimate approx. 5 FTFs total. Their Super Colibri is VERY good quality ammo.
