I personally have no use for a shoulder holster, but I think they're application is more for suit and tie dress. Your holsters depend on you individual needs. I personally have two holster types. Drop leg for cooler months when I may wish to wear a jacket, or a paddle. though I usually rock a leather bomber type jacket in the cooler months, so I can just tuck the jacket in behind the pistol grip. what usually becomes a problem is if you want to wear the jacket with the zipper undone. I may inadvertently conceal my firearm. Though I could go get my CCW and not worry about that, I just don't think I should have to pay for and have a permit for something that's a fundamental individual right.
