Either of those will be just fine. I'm not saying it's impossible to pull the slide off a 92FS, but I think that's something we can pretty safely keep in the realm of Hollywood.
Btw, it happened in another movie also. Jet Li stripped Martin Rigg's (Mel Gibson) 92FS with one hand. That was always one of my favorite moments in the movie.
EDIT: If you're worried about being disarmed either through disassembly or otherwise...carry a backup.
