Reminds me of a product I have called a Safepacker. Pretty much a wallet/planner holder style holster made from heavy duty nylon. Used it to pack a full size pistol on my motorcycle. Was very comfortable for all day wear, but a few people I know feel that holsters like this just scream 'GUN' to anyone looking at you. I feel otherwise.
