I bought eight hi-cap Pro-Mags for my Glock 34. Not ONE worked! Jamamatics in my G34 and in my friend's G17.
- Slide would lock back only "sometimes".
- Loaded rounds came flying out of the gun when the gun cycled! (I never even heard of such a thing before this!!)
- Even with ball ammo, rounds would "tip" downward, catch on the mag, and fail to feed.
ALL of these problems were sporadic but happened with all eight mags!
I took one apart and found rough spots all over the inside of the mag. By removing the rough spots on that mag (with a file and sandpaper), it seems to work better. Re-construction is still in progress.
I would not recommend Pro-Mag for 9mm Glocks to anyone. However, I've heard compliments about Pro-Mag in .45!
Be careful and good luck!
(PS. I don't get to this forum as much as I would like. Feel free to e-mail me if I can help.)
