I've had a lot of experience with the Mosquito since they were brought over by Sig. I got to shoot one of the first imported models at the factory more than 3 years ago.

I found that the Mosquito works best when you lubricate your ammo and use the light recoil spring or use a suppressor.

To lubricate the ammo I put 50 rounds of ammo in a shop towel, drip 3-4 drops of oil onto the pile of ammo and roll the ammo around in the towel so all of the rounds have a very light coating of oil. The use of the lighter recoil spring allows for better extraction and full stroke cycling.

The use of a suppressor increases back pressure which gives the side more power to cycle.

The triggers on the Mosquitos are absolutely terrible. I've been able to fix them by smoothing up the DA and SA modes, but with the internal mechanics of the gun, I can't make the DA any lighter.

One of the biggest cycling issues I've discovered with the Mosquito is the amount of over cock the hammer has. Over cock is how far the stripper rail has to push the hammer farther down after it's been recocked. The additional over cock means the slide needs more momentum to over take the hammer and completely cycle.

Just my 2 cents
