RE: Remington 597??
I have one in 22LR. Just the standard model with a plastic stock. It shoots very nice, and after I figured out not to overtighten the rail screws, does not jam anymore.
It is a royal pain to dissamble IMO. I haven't found a good way to get the springs on the rails in one try. It can take me as long as an hour and dozens of attempts to get it assembled.
