If you haven't already seen Dave with HR Custom Holsters, do it. Great guy and great holsters. I have several of his and several Crossbreed Supertucks in horsehide. I stick to HR now because faster turn around and cheaper.do yourself a favor and get one by HR Customs. Best holster there is for concealment. Local too, I believe retired military. Lives on Navarre beach. PM me for his number or do a search for him on here a-1 in my book.
I bought both, planning to use the medium for my S&W M&P Shield 40, and the small for my LCP. I found the medium is slightly longer and dropped the gun better past my hip joint, so even when I'm getting up and down I don't even know its there. And it still pulls out very smoothly. I've tried dozens of others, and so far this is the one that I use everyday. Very comfortable. Works in shorts or long pants - just have to have a belt.Why the medium instead of the small?
