I'm a very happy shoulder holster user. My EDC weapon is a RIA 1911 Commander .45, I just could not find a holster that was comfortable on my hip.
The biggest problem was driving , I just could not make it work, the weapon was captured by the seat belt it also dug into my hip and leg. After much thought
I decided to try a shoulder rig, I bought a $12.00 nylon horizontal shoulder holster just to try the concept out, it worked out perfectly no more hip or leg discomfort
and I had access with the seat belt fastened. During my search for a quality leather shoulder holster, I saw an ad for a used leather Miami classic style rig for $40.00
and took a chance. It turned out to be just what I was looking for ,it also included a two pocket mag carrier on the opposite side. I couldn't find a mfgr. name on it but
it's very comfortable and has never let me down. That 1911 fits very well under my left arm and is totally out of the way, the twin mag carrier balances well on the other side.
Now I'm a happy delivery guy!
