Sig Mosquito problem

[GLOCKBOY]

I picked up one used. It had the polymer mag. I cleaned it well, used a dry lube and shoot Federal bulk pak thru it. I get about 1 jam pet 50-75 rounds. Not great but better than some. It is a fun gun to mess around with but I may not be as happy if it was my only .22 pistol

Have also done a LITTLE polishing, not grinding, and mine functions great with Mini Mags. Sometimes I get a FTF and spin the case so the pin finds the primer. Have her learn on the Mosquito then get her a real Sig.
