I just got one today, and as I expected, it fits perfectly in a Don Hume J.I.T. leather holster, that's carried another half dozen or so small guns over the years.
Looks just like this one.
They sell new for about $35.00 plus or minus. I've had a couple for years now.
I forget what I originally bought mine for, but the BG 2 fits perfectly. On the back it's marked as a No. 70, and KM 9. Now that I think of it, it was probably for one of those mini Kimber 9mm, 1911's I had.
Sorry, Kydex, I got no idea.
