I got a NIB 2001 dated 597 today for $100 OTD. It has the old ejector and plastic mag. I read all the old 597 threads last night and went over it thoroughly when I got it home. I loosened the rail set screws to finger tight and dry lubed the rails and bolt rail grooves. I plan to wring it out tomorrow at the range and may give Remington a call if it's a jamaholic to get the new style ejector and metal mag. It doesn't look like the trigger is all that complicated, so I may try lightening the trigger sear spring too.
