Same problems as many have stated on here. Feeding problems, jamming, etc. Worst part is sgm's customer service. Sent e-mails over and over for weeks...still sending messages....nothing. No questions asked warranty is usless if the company won't even respond to answer it. Done with sgm...the one star is for customer service if nothing else. KS on the other hand has been great.

Horrible quality, feed lips bend, misfeeds

Review by Danney K.
Verified Buyer

I took the magazines to the range and every single one had stove pipe feeding problems. The feed lips also bent on each one simply the sneering them and light tapping them to ensure they were seated properly. The metal is extremely soft and bends very easily. I would not count on these in a life or death situation. I’m sticking with the G21 factory magazines with Kriss extension.
