If Sig ever figured out how to build this gun to high standards I'd buy one again. But...
I dont know that SIG is actually building them, just like I dont think Walther is building the P22. When you disassemble both and compare them, they are very similar.
Yep, but mine was only OK accurate.
I think you need to decide what your looking for before you buy any of them. The Mosquito and P22 are not target pistols by any means, nor are they trying or claiming to be. They are more than accurate enough for casual plinking, and if you want a gun that closely simulates your carry pistol, the Mosquito works very well, even with its somewhat odd and heavy DA trigger. Once you've played with it for just a short while, you dont even notice it. Then again, if its bugging you, and you continue to dwell on it, you might as well just get rid of it, as it will never get better in your mind.
Oh yeah, extra magazines are unbelievably expensive.
What other .22 pistol mags have you bought? The SIG's is $29. Rugers go for around $24, Browning Buckmaks are around $26, and I believe the Kimber mags are around $32.
I'm curious, but how many that had problems with their Mosquito (it was YOUR pistol and you did give it a good chance, right?) tried different ammo/spring combinations, what are your cleaning habits, and what are your experiences with .22's in general. I've owned .22 pistols of all types from most of the major makers over the years, and they all were finicky with ammo they didnt like, even more so when dirty, and usually all of them started to act up not long after shooting 2-300 rounds. .22's in general are also not the most reliable and consistent, when it comes to firing, and I have yet to shoot any of them with out a "fail to fire", which had nothing to do with the gun, but was ammo related.
I also find it kind of amusing that the Mosquito is junk, but the P22 is great, and vice versa, depending on who you talk to. Both are basically the same gun internally. I own both, and both have been flawless, and I guess I've been lucky, as neither is very ammo picky. Both dont like low power "target" type ammo, but then again, both recommend "hot" ammo be used. They both do come with two springs to adjust for ammo of different power, and both of mine seem to work well with the lighter spring that came installed. Both also came with extra front sights to allow you to zero ammo that works best fairly closely. For all that had troubles, both accuracy wise and function wise, you did make use of these before you declared it trash, right?
