Sorry for all the random pictures. I was glad to get it completed. It took a couple days to think out how I wanted it done. Then a couple days here and there to put it together.
There are 4 eyelets that I placed in the elastic band. The T-nuts go through these eyelets up into the holster back. The screw/washers then screw into the nuts. The importance of these eyelets is so that when the band gets sweaty/grimey, I can remove everything and hand wash it. Then I'll be able to reassemble it and everything will match up perfectly still.
I know I have more invested in this holster than I could have bought a cheapo one for ($13 at CTD). However, it is made how I wanted it and it is rather comfortable and suits me well.
I used 2 snaps because the HP22A is a tad bit smaller than the P64, so it makes for better retention that the strap be snug for it.
Thanks for looking at my pictures. Maybe it'll give some other folks some ideas as well to improve upon the design.
