I have a bit of girth myself. I carry SOB with a Springfield 1911 as well as shoulder. Just depends on the occasion or if I'm driving long distance. If I'm carrying my 357 it's with a clam OWB at the 4. With cooler temperatures coming, wearing a untucked shirt will become more comfortable which means I'll carry more shoulder most of the time. Accessibility and comfort. Keep looking till you have both. My shoulder carries with the weapon parallel to the ground verses vertical, smoother draw and max comfort. ALSO with a shoulder you're able to carry duel mags for back up.
