MOGC: Great advice.
I have 5 Model 17's right now two are unfired in the box 8 3/8" barreled guns and the other 3 are 6" minty models (no boxes for these).
Every once in a while I get the urge to shoot one of my 8 3/8" pistols off of sandbags just to see how well they shoot - but have resisted to date. They are just to valuable in their unfired condition.
Plus the 6" barreled guns shoot better than I can anymore, I am sure.
IIRC the very similar Model 18's in 22 L.R. were only offered in 4" barrel (I have two of these) and I am still trying to figure the other differences (if any?) in the Models 17 and 18 Smith's?
Hold into the wind
