EDC has been a real battle for me. At 160# and 30" waist I simply couldn't conceal. IWB, OWB seems no matter
where I put it, it prints. Well, I feel it prints. Auto or wheel gun. I tried all kinds of holsters, pouches and bands. If I were to put them up on ebay I'd be able to purchase another pistol or two. Then watching a rerun of the old Robert Stack Untouchables I saw how shoulder rigs seemed to work well. That's my answer. Tuck that baby in my arm pit and done deal. Horizontal rig with my Glock 23 was perfect. My small T shirt, the rig and then a LARGE outer shirt completes the ensemble. Reaching in the outer shirt gave quick access without hanging up. Feeling comfortable, the wife saying it looks sharp and conceals well. For several months I was all set. All set until shopping at the grocery store one day. I suddenly realized that in the checkout lane, every time I faced forward my Glock was pointed at the lady behind me and her two kids that were riding in the cart. That holster went in the pile with all the rest.
I was beginning to think that my only option was the gym and to bulk up. I know an instructor that is good sized fella. He carries a Judge in his pants pocket!
Preferring a shoulder rig I looked some more and settled on what has become perfect for me. A Vertical holster. The Glock tucks up nice under the arm. The muzzle nor the grip are pushing my shirt out to print at all. No adjusting to drive and then again sitting in the Lazy Boy. There be a Barney Fife incident it should be restricted to my foot.
Best part of using a shoulder rig is when out for dinner and have to hit the men's room. No worry where my pistol is while seated in the stall. It's still neatly tucked under my armpit at the ready.
