Good for training?
Review by D Otis

I bought 4 mags. 2 of them do not fully eject from the receiver. They hang up about 2/3rds of the way out. Kinda reminded me of the old non-lined glock mags. Not a huge deal at the range and I can work that into my training. The other 2 don't move at all when the mag paddle is depressed. I've tried everything to get them to move and they just sit there. They do come out when I manually extract them. This occurs when empty or fully loaded. Over all for the price and my intended use as range mags I'm feeling okay about the purchase.
Just as pictured.
