Well, if I carry it cross draw like I was planning, I'll have to move my extendable, which I really don't want to do. The thought of support side draw never really seemed to cross my mind, so what I'll do is put it on my duty belt in both locations and see which one feels the most natural.
If I was really paranoid, though, I'd see if I could find a three-point holster for it, but I don't think it will be that much of a problem.
