Which one did you get? What made me fall in love with the Walthers was the P-22 I bought my wife. It's the one with the long barrel with the fake compensator. It had such a Modern, eye catching high tech design to it that made it impossible to keep my hand off it. It lead me to this site from a Google search about them and it showed a posting by shipwreck. After joining this site I ended up getting back into guns. Now I have two safes full of them.
It was a pain to take off the compensator each time I field striped it. I thought it would wear off in no time so I bought a small barrel and now take it to the range more due to the ease of cleaning it. It took me an hour to try to put it back together the first time and it's the first pistol that I had to read the manual on how to put it back together. I even figured out the MKII on my own. That's why I asked which one you got.
I find it strange that they have so many options for the P22 and not the P99. I even heard that special forces carries the P22 sometimes. I'm still trying to figure out why if that was true.
The best thing about the P22 is that it's fun. I would not buy it for competition because it's so light it's hard for me to shoot it fast and be accurate. My wife out shoots me with it and she is not that good yet.
Have fun with it. it's a blast period.
