So it appears to be a well made fairly well thought out product. That being said I can not trust my life to it. Fmj never gave it an issue always feed after a 1000 rounds of fmj not an issue. Now to the problem… hollow points the round that you would be carrying in a self defense situation not as reliable. Regular 115 grain basic hollow points were fine. 147 grains gave me the most issues out of every box of 50 3-5 on average would fail to feed. Followed by any hollow point regardless of grains that had a little rubber tip. Simmilar results 3 on average out of every 50 would fail to feed. This in my opinion is something I couldn’t live with in a self defense situation. Were the mag I use could fail at the time of crisis. Magguts you are on to something good here please look at these issues. Which after a quick google search seem to be fairly common. And figure out what you need to do to make it work 100% all the time. I will only use it as a range mag at this time. Hope this helps anyone else trying to make a decision. If nothing else please test one of these with the ammo you intend to use to ensure it works reliably.. don’t just stick it in there an never check you are putting yourself in a bad situation.
