I have a bit over 300 rounds through mine. It has been 100 percent reliable since opening the box. I've fired FMJ, Hornady XTP and flat point, truncated cone lead handloads through it and it ate them all with no problems. You WILL want to get the grip extensions for the magazines.
You will most likely want to take a box cutter and carefully shave the mold flashing off the rear of the grip and the inside bottom of the trigger guard as it can be pretty sharp and painful when shooting it if you don't
If you get one that still has the polymer magazine release, call or e-mail Kel-Tec and request the steel one. Any practice dropping and re-inserting the magazine will quickly tear up the polymer one. It was a no charge item to me and they didn't even ask if I was the original owner or what the serial # was.
Accuracy is, of course, so-so, though you should be able to keep 'em all in under a foot at 15 yards, even closer if you have one of the lasers installed.
Recoil impulse feels less than a Walther PPK in .380 or a Makarov in .380 or 9 X 18 because they are straight blow-back and the PF-9 fires from a locked breech. It's quite manageable but don't "limp-wrist" the gun. I tried it and it didn't malfunction, but with a loose/limp wristed grip, recoil WILL be painful and sharp enough you might accidentally drop it. Not a good idea if up against a bad guy who's shooting back!
Double action only trigger pull is a bit lighter than the PF-11, but still has a long throw. It IS fairly easy to get used to and it is lighter than most D/A revolvers.
I am happy with mine and carry it all the time. Hopefully I'll never have to use it.
