My NIB 1979 SAA is a little stiff. Cosmetically flawless, but mechanically New. It was nice to hear 4 clicks 30 years ago, but now I wonder whether I should be hearing 4 GLASSY clicks : ) That's the sound from TV and movies that started me on this journey anyway. That, and history. What say ye? A gun this new (35 yrs) isn't exactly collectible, and though it's NIB, I may in fact shoot it. I'm old and there isn't much time for preserving things based on arguable collectibility. Can I, should I, have it tuned up, and let a good smith do (Bob James?) what the mfg should have done back in the Carter days? Thanks.
