May not be a good idea to store it with the hammer cocked. If you need it in an emergency, you're going to have to unzip the case to get to it anyway. Maybe it's safe - I haven't used those; I use a Sig in which case it's safe to carry it in the "de-cocked" position.
OTOH, if I needed to carry a pistol on a SAR mission, I'd rather have it exposed so I can get to it faster.
Just my $.02
