THE S&W M36-1 3" 38SPL is one of the greatest snubbies of ALL gun history. Mine would literally outshoot all three of the COLT PYTHONS I had with any 38SPL load you cared to test. For some reason I cannot explain the 3" BBL's on the S&W snubs were head and shoulders above the 2" snub barrels, far more that an inch of rifled barrel would leed you to believe. My 3" M940 is the same way, No fooling.
And so it goes...
