I bought my kid a 597 for xmas in '08....he put maybe 100 rounds through it and pronounced he didn't like it. Been sitting in my safe ever since. I have my own .22 semi thats my "go to" plinker so I never use his. (Hes moved away and left the gun here with me).
I put it on the EE but never got any takers. Maybe I'll try the Volquartsen hammer to improve the trigger pull. That was his complaint.
Or,...maybe it'll just sit in the safe.
