As usual, Buds delivered my new sidearm with lightning-like efficiency. I ordered it Friday morning at 0700 and it arrived at my FFL by 1600 the following Tuesday (and Monday was a holiday).
This Sig Mosquito arrived in a nice Sig/Sauer padded hard case with several extra parts (i.e. front sights, locking tool, recoil spring, lubricating oil, etc.). I know the Mosquito is prone to feed problems when you do not use the recommended CCI MiniMags, due to the fact that there is a small lip between the feed ramp and the barrel... The lip on this Mosquito is bevelled to prevent feed hang-ups. I have yet to take it to the range, but I will next week. My only complaints would be that the slide is matte black instead of the glossy black of my friend's Mosquito. This isn't really an issue, but it didn't specify one way or the other in the descriptions. The other complaint is that it came with only one magazine. Other than that, this is a splendid little sidearm... Extremely well built, tight movements, ambidextrous safetey, de-cocker, and best of all... It fits perfectly in my hand.
I'll post range results as soon as I can.
