It will be nice to see what Tom comes up with for a minimal bulk kydex pocket holster.
However, since a small revolver is relatively bulky compared to normal pocket dwelling items; it may be a case of "if you cant beat em', join em" (embrace the bulk). Paying homage to the great idea Mr Greg Kramer had, I made a pocket holster. This is my latest diy holster, I like it so far.
Is that a big wallet, or?...
just an LCR in a pocket holster, I call it the Black-K (kind of like black sheep); its a blackhawk/unclemikes size 03, with a piece of kydex hot glued to it. The kydex was molded to a very large wallet.
Thickness comparison to a BG380 in a super fly holster.
