I was looking at both the Mosquito and the P22. The more that I looked in to both the more disappointed I became. Both early models had problems (FTF, FTL, FTE). The Mosquito seemed to be made for my hand, the P22 seemed a little small. After talking to owners it seemed that the later models of the P22 seemed to have had all the bugs cleared out so I bought one. I had a blast at the range. 200+ down range only one fail to load(had a weak grip on the gun) using Wallie World Federals. I only wish that the wife liked the Mosquito more, I bought it in hopes that she would come to the range with me.
