    Recommended by mfg of my pistol (Phoenix Trinity). So far, everything as expected: drops free, no F2F, expected capacity. Well made.

    Baller Quality - Winner Reliability

    What's the say. Best 2011 mags. No longer need to have custom tuned mags. These have worked in every gun I've tried. My fully custom, my tuned 2011 and my buddies customs. They hold 20 out the box and haven't had a single issue. Going to get a full set. Killer good.

    It loads bullets into my gun!

    Good magazine. Does what it should. No problem fitting 20 rounds into my STI Edge. Feeds reliably with no hang ups. Though I don’t know why that seems to be so difficult for 2011 magazines to do.

    I think this is hands down the best option for 9mm 2011. Works. Easy Peasy.
