I have had a Mosquito for @ 5 months, with well more than 1,000 rounds through it. I bought it because I wanted to find a .22 my wife could shoot comfortably which would simulate a duty pistol without the recoil. As it turns out, and to my surprise, I really like shooting this pistol. Mine was manufactured in March this year. For the first 500 rounds I did as suggested and only ran CCI Mini Mags through it. I did have a few FTF/FTE in the very beginning, but after @ 100 rounds that stopped, and the pistol has been 100% since then. After 500 rounds, I went to Blazer ammo, not thinking it would work well. In fact its working perfectly, as is now Federal Bulk. It does appear these pistols require breaking in with Mini Mags before trying other brands. What else can I say; it feels great in my hands, like a real gun. It is, IMHO, the easiest pistol in the world to breakdown and clean (I wish every pistol maker was forced to study this aspect of its design; this is a dramatic improvement over the Rugers, which I also own). Accuracy is good, when you use good trigger control. The trigger can't match a target pistol, but I like it and it forces me to concentrate on my technique. I shoot it well, but it took a number of sessions to learn how to. I do lube this pistol very well after cleaning it after each range session, including putting Hoppes Gun Grease on the rails and slide; the grease stays put, doesn't accumulate any carbon or junk, and keeps eveything slick. I don't know whether this helps or even explains my pistols very good reliability, but I believ in it.
