That is not an april fool's: Market it as OC-spray attachment. Perfect for LEO and civilians alike - keep your gun and less lethal with you at all times. Situation might chance from firearm to less lethal and vice versa real fast, and for accountability's and peace of mind's sake you don't want to end up using the wrong tool. This ensures you have them both at your disposal at all times.
This is a very useful product. I bought both sizes. No, I don't see myself wearing it or needing to wear it on body with a supressor. Where it is amazing is in my bags. I use the vertx holster attachment vecro pieces to mount it in my bags to hold the supressor there and it is perfect for that. A previous commentor mentioned using it as an OC spray carrier and I absolutely agree. I will probably purchase more for this use case.
