I use one off duty. Easy to draw from and havent had any problems.
I wear my pants kinda baggy Not like falling off baggy but just loose. And it conceals good. I have a few pair that are a little tighter and you can tell there is something in my pocket but you cant make it out to be a gun.
I have never used one of those expensive ones that are made out of leather I have always just used one of the cheap 9.99 ones from unkle mikes I think it is Made out of neoprem(sp) and had a few strips of sticky stuff on it so it sticks to the inside of the pocket.
I think I have posted a pick of it before. I cant remember.
