I bought a Winthrop IWB for my EMP and it's not working out too well. I'm pretty thin (in shape... Do a lot of mtb and running) and have a bit of a curved in back and my butt sticks out. So the butt on of th gun using the wWinthrop sticks out. The snaps seem to come undone easily too . Any suggestions? I was thinking of a pure kustom because of the preformed curve and multiple angle options of the black ops, or maybe a hybrid.
