Just don't try to shoot the hottest hyper-velocity 22lr ammo in Mosquito e.g. CCI Stinger, CCI Velocitor, Winchester Super-X 40gr or else gun's slide will split like mine did. I had it for 3 1/2 years, shot over 4.500 rounds of standard 40gr@1000fps and high velocity amo (40gr@1250fps) with no problem.
But then one day I decided to chrono-measure and compare some different HV ammo including those 3 above. I wish I never did
After few shots the slide split. It's made of some cheap alloy and can't be fixed
No help from Sig-Sauer here in Europe though, they wouldn't change my slide even if I pay for it. They said to buy a new 22 gun, so I did. But not Sig Sauer brand of course. Never ever anymore
