I bought mine "lightly used" from GunBroker. I had read about some of the issues, tips & advice concerning the 597 so I was prepared to do a little bit of work to insure reliability & proper function. The biggest problem seems to be that the set screws that hold the bolt rails in place are over-tightened. They should be just touching
the rails and Loc-tited (blue!
). Another thing I did was polish the snot out of the rails & stone and polish the under side of the bolt. I also like to use a moly grease on rails, etc. when I'm breaking in a new gun. But, YMMV...
I've only had time to take it out once so far, but it shot ~100 rounds with ZERO
problems. Even with the cheapo factory scope & pretty heavy trigger, I was able to shoot several <.5" groups with CCI SV.
It was also pretty accurate with Mini-Mags, not too bad with Lightnings & Blazers & so-so with Federal 750s.
