My question is this, is there a formula or method for determining how far out to stitch the outline of the gun itself? From the research I have done, most seem to say a half an inch. The thing worries me is that the gun I am making this holster for is a Kahr and I am thinking that would be too much, but I don't want to just guesstimate. So is there a formula using the width of the slide to determine how far out to stitch? Thanks Shawn After I am done I will post a pic and while I can take and welcome constructive criticism, please be gentle.
