I know I've asked this a year or two back. Someone suggested a Vedder and I couldn't get the thing to fit properly, so I'm back.

Does anybody (good) besides Vedder currently make a holster for a P99AS? Or, is there a Canik with the exact same fit? JMCK has always been good to me and has a few offerings for Caniks and a few for other Walthers, just not the one I need or at least not by the right name

Call JM Custom Kydex and ask.

Any PPQ holster should work.  I'm considering ordering one from T Rex Arms because I can get it for the gun with a TLR7 attached (and with a QLS fork).  Besides that, I found an older Bianchi belt holster for a P99 on Ebay that I bought.

I have had good luck with C&G. I have one for my PDQ.

I prefer hybrid holsters, and use a Crossbreed SuperTuck holster on a daily basis.
