Back when I was young and gun poor, I had a choice of two revolvers in the drawer to carry for dinosaur defense - a 2" 10 and a 3" 64. I found the 3" stabilized much better on the belt in identical holsters due to the additional leverage from the longer barrel. Plus, I shoot 3" guns better. The 10 is long gone, but then 64 is still here and still gets carried on occasion.

As a matter of fact, I've considered rebarreling my 442 to 3"...
