Purchased my first kydex from Henry. This was awhile back when I purchased my first 170T. Not sure where I purchased my backup Kydex. I'd check out Henry's dealers, see if they may have one in-stock.
If not, check with Jim, over at Force Tech. He makes Kydex holsters for HDS. I bought a bezel up kydex with the Tek Lok belt loop for my Fury, and P1R. Excellent quality. He does have a 6 week plus lead time though (you'll see his note, re. lead times at the top of the web page).
