I've always enjoyed shooting 22 pistols and have owed quite a few over the years. They are great fun to shoot and a long day at the range won't break the bank. My favorite is my Browning Buckmark 5.5.
Don't own one. I've shot them before, great entry level guns and lots of fun.
However, with my high volume shooting habits and my evil gun qi (behold, I have become Death, destroyer of guns [I can break Ruger revovlers]), the P22 is not for me.
