Ive had a 522 for almost a year now. Lots of fun. Very reliable. Parts are NOT hard to find for them. Sigs website has tons of stuff and ive seen mags,sights and others odds and ends at every gun show ive been to since I bought the 522. It is on the expensive side for a .22lr. But the accuracy, reliability and Sig name make it worth it IMO.
