gavingear, the strap would help keep the mouth open more if it wrapped around the holster all the way. As it is now, it certainly helps in keeping the mouth open and gives the muzzle something to butt up against when reholstering. It almost serves as a guide, if that makes any sense. I think it's necessary - at least, on this type of pattern. I made one for my XD40, and it's become my daily carry. This version (P64 - pistol is almost a duplicate of a Walther PPK) lets the pistol ride high enough for a solid grip, yet low enough the conceal really well. Plus, the pistol wants to hug the body, which is also desirable. We'll see how this H&K comes out.
Without this forum, I wouldn't know anything that I do now.
