Well I was at my FFL 2 weeks ago and there in the display case was a Sig Sauer MOS22 aka Mosquito. After looking at the pistol it has had very few rounds put down range. I looked at almost every video online both pro and con and decided for the price I couldn't go to wrong. If it has any issues I don't think it anything I can't fix.
Besides it's a great trainer pistol. I got it home tonight did an inspection and cleaning. The bore is pristine and there is no scuffing on the barrel or slide. All the original paper work and hardware are with the pistol. The only thing I found is the recoil spring was installed backwards. The spring has different diameters at each end, Sig states the smaller diameter goes to towards the read of the pistol. This can create feed and ejection issues. Well some Militec 1 treatment, cleaning and it's off to the range next week.
