Mine is the 4.25 inch. Has been carried all over the Beartooths and the big horns. Round count is over five thousand by now. Replaced the front sight with a Dawson green fiber optic. Not the greatest for long range shooting but it does work ok for that. The first time in the mountain with that sight was certainly interesting. It was spring bear season, stopped on the way down to take a leak. Had to check the front sight out!!!! Green glowing dot despite it was dang near dark. Six inches of snow helped the ambient light but my partners sixgun sights were invisible.
The model 69 with x frame modified grips kicks less than an N frame and carries easily in a chest holster. Conceals fairly well under a vest, I carry two or three speed strips for spare ammo. My load is a 250 Keith (#503) at almost 1200. The same bullet cast hollow point runs about 1260. Makes a mess of picket pins and rockchucks.
