I enjoyed the Mosquito I had, but it's been gone for 5 years or more now. And I don't think that I've ever wished to have it back.
It was my first impulse gun purchase. It certainly wasn't the last.
I don't think that its disappearance is going to leave a hole in the market.
Had one, sold it to get a "real" Sig 229 classic .22.
Very happy with the 229, and have acquired a .40 centerfire kit for it from Central auto parts, and a .357 barrel from Maui Wowie on Sigforum. Both sources good to deal with.
The centerfire upper is flawless, and the .22 runs great till it gets seriously caked up. Meaning several hundred rounds.
I wonder if the new .22 is the .22lr version of the 938? I was surprised to see that they were offering a variety of 938 versions in .22, including a longer barreled version and a TB version.
Because the early early early pistols made 10 years ago had some documented problems, and this is the internet ... So nothing ever dies, and only the bad things are remembered... And this is an internet gun forum, so you have to consider that +90% of the opinions posted here are influenced solely by other inexperienced posts that person has read on OTHER gun forums. Basically, you have to take things with a grain of salt here, and expect ignorant people to spout off about gun they have never owned.
I've had two Walther P-22s, made in different years, produced after the updates. Both were totally reliable with every 22 ammunition available - The first one i had fired around 10K carefree rounds through before the zink slide cracked. The second one I did the "Bible" mods on out of the box, and it was still going strong about 5K rounds later when I sold it to a friend.
The triggers were mushy and terrible on both of them, but they were very reliable, and accurate enough for what they were.
I CANT say any of that about the Sig Mosquito I got for my mother. It has never run properly with anything but CCI mini mags, and sometimes it doesn't even run with that.
