Well it's a yes, and a no.
If I'm going to town for what ever reason, it's always the same handgun, in the same spot, appendix carry, always.
When I'm working it's a revolver in a flap holster carried cross draw.
When going out to excercise some other handgun, it still never changes.
I believe that im going to transition to the only appendix carry, simply by having essentially the same pistol, but a shorter bbl for more flexibility.
Muscle memory and different locations may at some point be a problem, as I dont spend as much dry practice time with the revolver on its position.
