My Monson, 6", Blued, Vent Rib, Full Lug, Heavy Barrel .357 was
the most accurate revolver I've ever owned. Never a problem, reliable with all ammunition, and a wonderful trigger.
Naturally, I traded it away.
I've been kicking myself ever since.
That weapon would easily outshoot any of my Smith N/L/K-Frames and was more accurate than my Python. It was damn near as pretty.
These days, I've got a 4" .22 version (which also shoot like a laser).
Treat yourself and buy it (a Model 15...not the earlier Model 14 with the exposed barrel nut).
