I would buy them again
Review by john
Feels like good quality. Got them for an h&k compact witch normally have 8 round mags so these are great for extra rounds. I put 15 rounds through each (bought two) and had no issues at all. Wish I got two more when I had the chance.

Good mag for the range, because they get stuck a little on release.. but run them a few times and they start to drop out smoothly.
