The 597 is my first and only gun, I was looking for a bolt action but due to selection I couldn't find any, but the shop owner told me in my price range the 597 was dead on. (wasn't keen on a semi-auto but ah well)
I found the only problem was a magazines, at first the stock magazine would not fit all ten rounds, that changed after putting about 50-100 rounds through it
I bought a second magazine, same issue found that opening it up and turning the spring backward solved that problem (no feeding issues after 300 rounds)
The one issue I am having is the "Auto Hold-Open" isn't so auto anymore, it works when it wants to, I'd say about 80% of the time.
I am pretty sure its due to the spring strength of the magazines I am going to look into it further when I have the time..
I am very happy with the 597, shot great right out of the box at 25-50 yards, decided to scope it which even for a newbie was easy for me and its incredible, I have been able to out shoot my friends Savage Mk II consistantly.
