Well, I took a chance and picked up a PPK BRNO KMS 617, and it functions really well. No FTF/FTE, had a few misfires on the first few mags, but that may have been due to the cold (-25) or the fact that it was a new gun, or both (?). Either way, by the time I got half way through the first box, there were no issues. Accuracy was good at 50 yards, despite the thin barrel profile. I'll have to take it out to 100 to properly check the accuracy. I mounted a Burris E1 Fullfield 3-9x40 on a Mossberg 500 picatinny rail attached to the receiver (I didn't like the strangely sized dovetail that came with the gun so I drilled and tapped the receiver).
Oh, and sorry for the thread resurrection.
