Jo-Brook Firearms in Brandon, Mb., has hammers and extractors for the Remington 597. Only a few more dollars than the suggested US prices too.
Phone number is 204-727-3552.
I really recommend the hammer as it takes the heavy trigger pull and really lightens it up --mine is a hair over two pounds now. I bought an extractor but my rifle has not had any problems with that area yet, but if it does, I will install the extractor.
It only takes about 5 minutes to install the hammer. Use a slightly smaller slave pin to line things up, then the factory pin can be installed.
Big thing with the 597 is DO NOT tighten the guide rod screws up too tight. You will bow the guide rods, causing them to drag on the bolt, resulting in FTE malfunctions. Just tighten them finger tight, then back off 1/4 turn. They will not work loose.
Forget about Remingtons 10 INCH POUNDS of pressure on the guide rod screws. That is .8 FOOT POUNDS of pressure and no one can really get it correct without very sensitive tools.
You should do the guide screw pressure loosening then try your rifle again. Put about 250 rounds of CCI Mini-Mags through it to break it in and see how it performs after that. Also, some people tend to jam the recoil springs up against the back of the bolt, and they drag slowing down the bolt when it comes back.
