Rook, gross.
Okay, you asked for it. First time posting images, wish me luck!

I prefer to use metric measurements myself, but as this piece seems to have been designed in inches I thought I'd stick with that. Just not so easy to type the fractions!


The recessed shape on the face of the holster appears to be repeated on the back, leading me to surmise that the holsters could be made left-handed by swapping the metal piece to the other side. (Sorry if this is common knowledge..?)


The metal plate is 1/8" thick. The part the belt goes through consists of a sandwich of 1/8", 1/4", 1/8" (=1/2").

This last one shows one of the three fixings on the inside, corresponding to the screws visible on the back. The screws must go into them like a nut, but it's not a fixing I've seen before.

I didn't note a thickness for the holster plastic; that's because it varies a
lot. However a rough average would be 1/4" overall, thinning to 1/8" for the recessed detail.
Well, I hope some of this is of interest. It's nice to be able to provide some answers for a change.
