1.75"-2" barrel in my experience. But like others have said, depends on frame size... S&W governor has a 2.75" barrel, but it is a huge frame, so it's a snubby... You can find 2" barrel K frames but they are rare, so maybe a 3" would be considered a snubby?

All these have 1 7/8" or 2" barrels...

S&W 36 no dash J frame, S&W 34-1 J frame, and Ruger LCR
