I bought a 597 in 17HMR as soon asit came out, matter of fact my dealer said before he got it they discontinued the grey laminate stock and went to brown. Came with a grey laminate stock, mounted scope rail and heavy barrel. I haven't had any problems with it at all. I have heard of the magazine problems on the 22s. Check out rimefirecentral.com They have a forum over there with a lot of info on the 597 magazines.
