I currently own a Pocket 9. As much as I want to like it for being light, small, and a great idea, I've found it very unreliable, even after a break in of a few hundred rounds.
I can't get through a magazine without a failure to feed or a stovepipe. I've tried various magazines (all expensive original Colt mags, as well as aftermarket OEM mags) without improvement. This is with factory ball ammo.
I can put up with the harsh triger that pinches me, but the reliabilty is unacceptable.
My 2 cents.
