Don't believe negative reviews

I ordered this to pair with an MBX mini PCC extension. I've seen tons of ETS reviews online that were pretty poor and I couldn't find Glock 33 rounders anywhere so I figured screw it let me give it a shot, especially for the price. I installed the MBX extension immediately and loaded up about 30 rounds, after that the follower started to cock a bit and bind so I emptied the mag and tried again, zero issues. I used the mag the following day at a USPSA match (brave/risky running it without ever testing it) and I had absolutely zero issues. If you can't find OE Glock 33 round mags and need something for PCC division this is a great alternative! So again, don't let negative reviews of other ETS mags sway you away, definitely try one of these out!
