I had two (only have 1 now) but it is a great pistol. Like everything else there can be bugs with it but it is almost always ammo related. In a nutshell, if you are looking for a .22LR pistol that "feels" and operates like a full size pistol, then get a Sig - it is like 90 percent smaller then a normal Sig. If you are looking for a pistol that will shoot everything reliably and never jam, then don't buy a 22LR pistol because I have yet to see a semi auto .22LR pistol/rifle that is 100 percent reliability - mainly because 22LR ammunition varies so much in terms of priming, bullet shape, powder charge, etc. If you want something is pretty reliable with lower costing ammunition - the Ruger Mark 2/3 semi pistols are pretty good and inexpensive. Just my 2 cents. I find that many of the people who hate the mosquito's, frequently dislike the fact that they can't buy the cheapest ammunition and have the pistol operate 100 percent reliably. I experience jams with Dynapoints/T22/etc but with Stingers/Velocitors it is very reliable.
