My ppks was very reliable, when I finally got it back from S&W service. It just would not work out of the box.
After they took their sweet time, to fix it , it was great.
shot fine, very accurate, no problems feeding any ammo.
I put a piece of pac-skin on the front and rear of the grip area to help control the muzzle flip, it wasn't to bad, but this did help.
sold it due to ammo prices, .380 is pricey around here, 9mm is a lot cheaper for practice.
