+2 Mag Extensions for Glocks 17/22/31
Ratings & Reviews
Very pleased with product! Bought 3 of these for my Gen 5 Glock 17 mags. Installation wasn't bad at all considering this will add +3 rounds to your 9mm 17 rd mags! I have used 2 so far and I noticed on mag gets 20rds and the other gets 21rds. I'm assuming that the spring is being over depressed when its loaded to 21 rds. But nevertheless a good product im going to run each mag at 20rds to ensure reliability. Has anyone else had this experience?
