I know leather and tack places are harder to come by these days but I would just find a shop and walk in there and see if they could make you what you want.

That's what I have ALWAYS done. That way the length and the holes, etc. are all in the correct place for ME. Not something off the shelf where it doesn't fit exactly perfect.

I think this is way more important for a pistol belt. If the holes aren't exactly right on one you order without putting it around your waste.... you'll be wearing it too tight or loose, etc. assuming you can even get the correct length.

See what I'm getting at?
