Stu-I just can't bring myself to use an AIWB holster. I ain't got much but what I do have I aim to keep.
I've also discovered in a short period of time that after about 8-10 presentations the leather has scuffed the finish on my 4516-1, mostly the sides and top. Maybe a nylon holster....
It's pretty warm down here and especially the past year or two where winters last about two months, if you want to call them winter as we didn't have such a thing this year. I'm on three blood thinners so, I wear a T-shirt most of the time except when it gets 85+ like in July-August. maybe I'll find the right combination-everybody does sooner or later. I just want something comfortable, a holster I can draw and reholster with fairly easy and one that won't scratch, mar my pistol. Maybe such a thing doesn't exist.
