The model 69 is a wonderful carry revolver. Replace the issue grips with Hogue X frame grips. Attack them with a belt sander to make them smaller and without finger grooves.
The idiot lock is easily removed, lots of YouTube university videos showing you how.
I have carried mine many miles in northwest Wy in a chest holster with a couple speed strips. Normal load is 260 Keith at 1190. Lots of varmint shooting with it and rocks way out there. It is my favorite revolver to carry and shoot.
Replaced the front sight with a green fiber optic from Dawson. Makes a huge difference for me seeing it against varying backgrounds.
