I usually use something similar, though usually a model that slides onto my belt. Keep it on the right side of my waist where rounds are handy to grab with my right hand (am right-handed). Also keep a couple of individual rounds in pockets, especially when using a single-shot, when I keep at least one in one of the chest pockets of my shirt or jacket.
