Lots of fun
I've got one of the little buggers, and it's a load of fun to shoot. Problem I have with mine is that the slide sticks... a lot. A lot of my shots are after I "whip the gun forward" to make the slide lock back in place. It also fails to chamber rounds sometimes, so as for a "carry gun", I would recommend something else... but as a range gun, they're loads of fun.
They're extremely accurate as a shooter when they're working, but I've done a bit of "smoothing" the rail slides and start off with a shot of oil on the slide before range visits. The rails seem to get nicked up during disassembly (the zinc being a bit softer than steel) so until I "evened" the rails up, they were getting shaped ^^^^^_______^^^_______ with nicks on the slide rails. A diamond file (small and flat) and a honing stone, and I have them reasonably back in a ___________________ situation (only a few bumps, etc.).
Mine was bought new, and I have no one to blame for dinging it up but myself, but a little harder slide material would solve a lot of that problem. I would even consider an aftermarket slide of steel or stainless steel.
If anybody at Walther is listening, they should produce a steel model of this gun. It's got a good design and it shoots great except for having to stop and either clean it or remake the slide rails work. As a bit heavier gun, it would probably be more accurate to shoot as well. The current version is easy to roll in your hand as you squeeze the grip, so you have some "art" to learning how to actually handle the piece as well.
I'm happy with it as it is, but I can see that an improved model of this gun would completely grab the market. Every weekend, I have people commenting about my shooting, and it's usually when I'm shooting the P22. Accurate small caliber shooting is more deadly than "maybe so" big caliber shooting... and at about 15 yards, I'd rather put 10 .22's into the center of my target than one or two of the larger calibers.
I like my .40 cal, my 9mm, my Makarov, my .357 and my .380's, and I'm accurate with them... but for plinking and just burning ammo... that P-22 is a shooter... and it's cheap to use.
