Thanks for the reply. I'm not really sure what I want. Just wanted to take a look at some in person, but it doesn't seem like anyone stocks them. I checked around and was told I might try the police uniform store downtown but they aren't open on Saturdays anymore due to the covid. Might try to stop in there another day.
USA 1, I've been wearing shoulder holsters of various designs for decades. It's important to get the right style. You're probably going to have to order one from online. And if you're barrel chested you need to think of another style. You won't be able to reach the gun.
For what it's worth I've gotten pretty retro in my old age and have a number of shoulder rigs (including a couple of two gun rigs) from El Paso Saddlery.
I have used the Galco Miami Classic and Jackass models for years. Shoulder rigs take some getting used to and you need to practice draws and reloads until proficient. I also recommend using wider straps on the front side. Disperses weight better and helps with comfort.
