I recently bought a Kydex holster from Armordillo Concealment. The short story is I really like it a lot. It has proved to be both comfortable and durable. Additionally, it securely hold my Glock 19 in place.
The price was reasonable, even with the semi-custom addition of A-TACS FG camo to it. I also bought a matching double magazine pouch with the holster that has been equally durable and comfortable.
Armordillo Concealment is a US manufacturer with all of the holsters being made right here in Florida. I’ve not had the chance to meet the owner in person, but I have swapped e-mails and a phone call with the owner. I’m impressed by him and his work.
