I've had one for a while. Cocking it automatically engages a safety that you have to disengage in order to fire. I've invited guests to try it, and even fumbling with it, no one has fired it accidentally.
If, however, one is beset by insects and doesn't have many child visitors, the safety can be disabled by moving the switch to the unsafe position and putting a screw into the plastic next to it so it can't re-engage.
