Tried homemade shell with a kydex sheet & that didn't go well. So I got brave & risked ruining my Alien Gear holster by taking the heat gun to it to try to accommodate the TLR-7 I wanted to add. It worked out and now I have a semi-custom AG holster that allows the TLR-7A & MRDS on a Hellcat Pro. Hope this helps other folks too!
