Lock n' Load
Custom
For those with "auto on or always on" red dots, I found a soft neoprene cover for my Shield RMSc from a company called Plastic Dreams online. I got 2 covers (they come in 2 packs) for very little money. They fit perfectly for battery conservation during storage and also protect your expensive optic. I don't use it for EDC as that would negate speed when needed. They make different models for some of the most popular red dots.
