YW. I am also a bit big and have trouble with some kinds of carry. If I need to carry for those short runs I would grab my fanny pack. Lots who wear sweat pants have them so it doesn't look too out of place. The rest of the time I wear a paddle holster on my hip. I also have a Milt Sparks (executive) for the 1911 but it is carried only when I can wear something like a jacket.
And, yes, I practiced a bit with the fanny pack so I could make a clean draw.
