Just want to say again, the absolute best thing you can do for your 597 is the Volquartsen Target Hammer and Edge Extractor.
I cannot stress enough the tremendous difference these two parts made when installed and have continued to make in my rifle. Best money I've spent on my firearms bar none, maybe the LimbSaver for my shotgun, other than that, really the best improvements I've made to any of my guns.
And while $20 and $40 is not peanuts, of course, it's not like saying "Oh you need a $600 scope to make it worth right" etc.
Just wanted to say how much of a difference it makes, and like on Rimfirecentral for example, everyone with a 597 that does the two VQ parts, praises Praises PRAISES it.
