Today is day three since I brough my little Pup home, 170 rounds so far, two cleanings and inspections and still shooting on the first recoil spring with no failures.
I've noted significant wear at the rear of the frame, which completely removed the finish at the rear end of the guide rails, but other's reported this to be self-limiting and I would suspect this is the case. The R9 is a tight little design and some break-in wear is to be expected.
I have nothing remarkable to report, the R9 performs like any other pistol, no bad habits, no difficulties, just press the trigger and she barks on command. I honestly expected some teething issues, as a design this small was bound to have some compromises. That assumption seems to be proved wrong.
So, now I've had two days at the range and several boxes of ammo to adjust my "love at first bang" opinion. Here's the adjustment: The PM9, LCP and P3AT are in the safe, the Pup is in my pocket, and that's the way it's gonna be.
