I agree that Kydex is not ideal. There's a 10 week wait on my holster, and I need something in the meantime to keep the LCP from shifting and printing. I have a ton of Kydex, and a DeSantis copy it's something that can be done in 15 minutes. I'll probably use something to increase friction with the pocket lining.
I did venture out Saturday with a piece of poster board covering the print. Worked well, but the draw sucked.
