I normally don’t use shoulder holsters, but I have one use case - my Miata. It’s narrow enough that hip carry is uncomfortable. I usually grab a 43 or more lately my P365, and use Safariland ALS shoulder holsters (yes, they are a thing.)
As I transition more and more to RDO pistols, I want to find a shoulder holster solution. I’ve never seen one - is anyone aware of any? Leather is fine, as is synthetic materials.
