I particularly like their ambidextrous mag release which is located at the rear of the trigger guard.
That's exactly why I had to get rid of mine. I don't know how, but I would inadvertently drop the mag out of the gun after a round or two, apparently from barely touching the mag release on the trigger guard somehow. This also happened to a friend that shot the gun as well.
I've owned Sigs, H&K's, Kahrs, etc. and have never had an issue (obviously because they don't have a trigger guard release), but I don't believe my finger is rubbing the trigger guard either.
Otherwise, I loved the gun. Felt like it was made for my hand. But I'll never take the chance of having a gun with a trigger guard mag release - of any kind.
