NOT a 9 round magazine
2 out of 5

The mags function fine, but they are not 9 round magazines. If you really compress the follower hard, you can get a 9th round into the mag, but you cannot then insert the magazine on a closed slide. Tried on my STI Ranger II and my Kimber Pro Carry 1. Can't get it into either gun with 9 rounds in it. They will work as a backup mag, but not as the primary mag in my carry gun. Will not do 9+1.
