The "King of the Hill" award in .22 pistols is a dead tie between the Ruger Mk III and the Browning Buckmark. You can't go wrong with either one.
Another really good pistol is the Beretta Neos. They are extremely reliable and accurate. The Neos, like my Browning, is one of the few .22s out there that will function no matter what you load it with. It's also the cheapest of the bunch. I had one and got rid of it for two reasons. One, the looks. Ugly with a capital UG. The other was the grip. The grip on that pistol is heavily slanted, and just did not sit well in my hand.
The Mosquito. Actually a decent gun, if you're willing to pay for premium ammo. Because about the only thing it will run on is CCI Mini Mags. Anything else turns it into a jam-o-matic. That and one notable design issue. When it does jam, it does it in such a way that it can crush the rim of the cartridge and bang......the cartridge detonates in the ejection port. Gun Tests Magazine stopped their test of the Mosquito and sent it back after it deposited brass fragments in the shooter's forehead.
Oh and those ATI and Citadel 1911 .22s are great guns. Reliable and accurate, but one word of caution. Some models (they aren't all the same) have a screw which passes through the frame from the right side, just ahead of the trigger. This screw secures the barrel to the frame. It's threaded directly into the frame. And the frame is made of aluminum....very soft aluminum. If you ever remove the barrel for any reason, or if you have to tighten the screw due to it working loose, be very careful as you can strip the threads in a heartbeat. And since the threads are in the frame, there's not much you can do about it besides replacing the frame. Unless you can find a good gunsmith who can plug the hole and re-drill and tap it.
