I just grabbed a digi cam sig mosuqito with a threaded barrel today, put about 400 rds through it with only 2 failure to feed. I am so far very happy with it. Ive been told you shouldnt dry fire a 22, so I havent yet. Does anyone have any idea where I can maybe get a more high quality mag that wont malfunction though? I really plan on putting alot of rounds through this and want to be able to not worry about it jamming. On a side note if anyone knows the process on obtaining a supressor I would be glad to hear it. Any input would be nice.
