    TTI has taken what was a 17 round magazine and made it hold 20 rounds. I know others have longer mags. that hold 20, but I really appreciate the shorter mags that allow 20 rounds. I have put a couple hundred rounds through them and they have proven to be reliable. Some of my fellow officers have switched to them also and have similar results.

    20 round capacity 2011 mags. Work great so far. I have some guns where I have over-insertion issues with MBX pattern magazines but these magazines, like the other checkmate magazines I have I don’t have any issues with ejector contact.

    The new checkmate 20 round magazines that fit in my Staccato are awsome. They fit and look better on my duty belt. They lock the slide back on the last round. Their reliable, what more could I want. Everyone should buy some.
