The armorer is supposed to do it for you. Supposed to take the gun away from you between takes as well - actors are usually not trained

It doesnt matter if you watch the person check it before they hand it to you. If you don't check and it goes off. You're responsible. Pretty freaking simple. If they " aren't usually trained" then they shouldn't handle them to begin with. The basic principles of handling a firearm should be known by anyone holding a firearm.
