I'm up to 300 rounds in my P3AT with no problems.
There is a "smiley face" issue, where the bullets hit the feed ramp, leaving a smile on the bullet nose.
No failures have been caused by it, but I'll be glad when it is cleared up.
With a shootable, controllable .380 in a package that small, KelTec has a winner on their hands.
This gun is much more comfortable to shoot than the NAA Guardian (.32) that I used to own.
