I have a flawless first gen 597 magnum. Lots of work to get there. Voltarsen hammer and McQuag springs, 3 Gen mags, polish the guide rails and bolt. The McQuag springs include metal bushings for the trigger group. I also replaced the sights with tech sights. Not an off the shelf firearm. Also the guide rails are too tight at factory torque and the soft receiver will twist, back them off quarter after torque. Go to Rimfire Central dot com a study the complete list of fixes.
