I was looking at the S&W15-22 and saw on a local gunshop website the sig522. I was unaware of this product. I had purchased a s&W m&p 9mm vs. a sig 9mm based on price. I later got a sig 22 mosquito. I am very impressed with the sig, and sort of wish i spent the $ getting the sig 9mm (but it was several hundred more). I don't want have buyers remorse, local ranges do not have these rifles so I am hoping that someone has direct experience with both of these. I have only heard good things about the s&w 15-22, so I know it isn't a bad choice. Neither was my sw m&p 9mm, but wondering if the sig522 is even better. Looking at this just for target shooting/plinking etc. Want very high reliablility , no jamming, can shoot any amno etc as most important features. Thanks.
