I've only used their 8 round in a Colt 1911.
I bought 3 at a very resonable price, and expected problems since they were so inexpensive. I was pleasantly suprised when all 3 worked great.
No failures to feed.
Always activates the slide stop after the last round.
Removable base plate makes for easy cleaning.
Spring rate makes loading easy.
Good Luck...
Joe
