How did George suddenly get the gun think back when did he have a chance to get the gun?

George likely got the gun during a moment of opportunity when he was alone with it, perhaps when he was handling it or when he had access to it without anyone watching. This could have occurred earlier in the story when he was preparing for their situation or when he was reflecting on their circumstances. The suddenness of acquiring the gun suggests it was a pivotal moment for him, possibly driven by desperation or a need for protection.
