I have several of this style of holster, made by DeSantis and one made by Alessi, and I never use them as cross-draw. I wear them strong-side hip, canted slightly forward.
What I like about these is that they have the mouth of the holster reinforced to stay open for reholstering. I carry a 3913 in an older DeSantis that has gotten a bit soft over the years. I really should add the reinforcing like this!
