Revolvers don’t have safeties at all.
Why didn’t you jump to the conclusion that it was a revolver rather than a Glock?
99% of revolvers don’t have safeties, because they are really not needed. For a DA revolver, they take an extremely long and strong pull, unlike the Glock. If SA, they need to be cocked first. The chances of a revolver accidentally or negligently discharging are much, much less than a Glock. Even so, most people I know who carry revolvers do so with an empty chambers. As someone said earlier, there is no reason to carry any weapon in condition one in cockpit with a locked door.
