Got a Miami Classic II (open horizontal mag pouches) for cheap when Virginia Arms Company went out of business. Had @JRCHolsters make a Glock 19M+Surefire XC1 holster component for it, as well as a radio pouch. Asked him to try and match the Galco color as close as possible, and I think he just about damn nailed it. The idea being that I could wear this if pulling watch in a vehicle for long periods. When I came onto my current assignment, we were pulling 12s in a vehicle outside the bosses residence, and wearing shit on the belt was pretty damn annoying. Both fortunately and unfortunately, we moved into the bosses house in a hardened command post, so the need rapidly disappeared. Very few people wear them outside specific niches like this (driving, sitting CP duties, back problems, chronic Delhi belly offenders that have explosive diarrhea with no warning, etc), and they have their limitations....but yeah, shoulder holsters are just plain cool.
I've got it mounted with the horizontal mag pouches right now, carrying 1 mag and a flashlight.
