I agree a six inch barrel looks great on a revolver. I’m looking to buy a S&W model 66 and my struggle is between a four or six inch barrel.
I’ve had my S&W Model 29 for Decades. 6-1/2” Barrel, 44 Mag.
My favorite Pistol. Grip is just right for my hand and it is pretty accurate, though I’m no Dirty Harry. LOL
IMHO - Short Barrel if you Carry, Long Barrel for Fun.
