Man! That is one good looking pistol.
Sorry I can't answer your question about holster availability but I'm very interested in those pistols.
I guess I'm looking for a range report with an eye toward reliability. A guy had one at the range a few days ago. He said his has been absolutely trouble free. When they first came out there were reports of reliability problems. Enough so that I didn't buy. Now I'm tempted to give one a try anyway.
How has yours been functioning? How many rounds fired?
Back to the holster question.
Holster availability can be a problem with a model that has not sold into the thousands or less. If you can not find a maker that catalogs a holster of the type you want you may have to go with custom made. Sorry, that's all I got. Good luck in your search.
Just buy a hybrid for a similar style/size pistol, use a heat gun to heat up the kydex, form it. Done. I got tired of looking and paying $100 a pop so I started doing this. I bought sheets of kydex so I didnt have to keep reforming but use the same hidden hybrid backer for several kydex shells.
