Worth it!


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?

Will be getting more!


Mag ext are relative easy to install and turn my 17rd mag to 19 rd mag. This is the economic way of getting into mag ext. Durable and tough!
