Hello everyone. Im here just to bring sone info on my relatively new Sig Sauer Mosquito. Very fun plinker. You may have heard rumors that it is very picky on ammo. This is true, but only for the beggining stage with the gun. After about 500 - 800 rounds through mine, I was able to fire cheap bulk ammo through it. At first only higher velocity rounds (1400 fps i think, dont quote me), i used 1430 fps Blazer ammo for break in, and now can use bulk ammo. So, if you held iff on this handgun due to the finicky ammo, GO BUY IT.
