I enjoy mine. It is as accurate as I expected. I suggest you stick with the 3.4" barrel, forget the longer one. So far I've had no problems with feeding both bulk and good ammo. The gun is fun to shoot, has great ergonomics, easy to see adjustable sights, very mild recoil of course, easy to use controls and an acceptable trigger (much better than a Sig Mosquito).
The only other gun I would have wanted instead of the P22 is perhaps a Firestorm (Bersa) .22, but finding one is not easy for some reason. They are the same price, hold 10 rounds and both appear to be good plinkers.
