Sig Sauer Mosquito
Review by
The Sig Sauer Mosquito is a .22 LR pistol.
the gun is about 80-85% the size of the P226 and slightly lighter. Mag holds 10 rounds.

Test fire the gun finally this weekend. Manufacturer recommend CCI Mini Mag, and most forums I visited recommended running min. 500 rounds of the CCI Mini Mag before changing it to cheaper ammo.

I ran thru 300 rounds of the Hollow Point, and then another 100 of the FMJ. Only had 3 issues. 1 - bad ammo, and twice the hammer didn't lock back (all 3 happen with the hollow point).

other than that, the gun fires like a dream really accurate, got a laser for it (from Sig Sauer), didn't add to much weight.

The gun was really accurate, minimal recoil. My friend's 8 year old son shot it, and he did a 6" cluster at 5 yard (4th time shooting for him).

Gun came with a different set of sights, and spring, but I just stayed with the whats in gun out of the box with no problem.

Did have to clean it pretty well before I went to shoot.

The finish is beautiful, will recommend it for other shooters.

I have owned alot of 22 pistols in my years but this is the most accurate semi auto out of the box I have seen. The full size grip allows cheap self defense practice at a great price. (Posted on 1/16/12)
