I'm 5'9", 190 lbs, and I'm carrying a Glock 36, the "compact" 45 auto, the same gun I used for CCW class. I'm right-handed, wear a vertical shoulder holster on the left with strap...and I STRONGLY recommend a retainer strap for any shoulder holster. Here's why: A few months ago, we had a lot of tornado action in the area, and I was out helping clear roads and property of fallen trees. At one point, I got my foot entangled and took a sudden fall backwards (yeah, I was wearing my old shoulder holster without a strap). Fortunately, I didn't break a leg; but, after a couple of minutes, I realized my damned Glock was missing! It slipped right out when I fell; in the excitement of the moment, I wasn't aware it was gone. I scrambled back to the scene, got on my hands and knees searching under the debris, and FOUND the damned gun. Soon as I got home, I threw my shoulder holster in the trash, went online and ordered a tactical-style with retainer strap. Don't leave home without it.
