I am looking for a shoulder holster to carrie a Colt Rail Gun. Back is hurting so doc said to take weight off my belt line so will leave the STI 6" 10mm off my belt once I find a good shoulder holster. I'm looking at seven different ones. If you have used one of the ones I am looking at could you give some feed back. I know a lot don't like but used the old vertical spring clip Safariland and Bianchi in my younger days.
