I don't know if he's still around, but I had several Kydex Gun Glove holsters made for me by Kevin McClung of Mad Dog Holsters (A.K.A. MD Labs) just outside Prescott, Arizona. I was able to specify the cant of the holster, the retention in pounds, and he made magazine holders for me, too. His process is the same no matter what kind of gun he's making a holster for, so it's irrelevant what kind of gun you have. If he hasn't made one for a gun before, you have to send him yours (or stop in like I did and get it while I waited).
The process that might seem kind of dangerous to some includes wrapping the gun in foil and then wrapping a hot piece of Kydex around it. It hardens in a minute or so, and leaves no trace on the gun. None of mine looked the worse for wear, anyway. The whole process took less than ten minutes and cost me only $45 per holster. Once I tried it out, I decided it was a little too retentive, and he heated it back up and took a couple pounds off. How's that for custom??
Again though, it's been a few years since I did this, and I don't know if he's still doing it. He was big into making ceramic knives at the time, and I don't know if that took over his focus. He even sharpened my Benchmade for me while we were chatting, no charge. Super good guy, and his stuff is top notch!
