Given the setting, Luke, anyone for that matter, would very, very quickly adapt to a point where being armed was the norm......it'd literally no more even occur to someone in that setting to disarm anymore than it'd occur to me or you to take our clothes off in public. It not only wouldn't be an option, we'd never even think of it.
I'd contest that: South Africa has a few stories of missionaries who refused to carry guns when facing other people, even when it was suicidal not to carry them (although some members of their parties inevitably did, if only for hunting). Some of them outright died as a result of being outnumbered when they invariably got the neighbours unhappy. And, giving colonial forces plenty of opportunity to go right into disputed territories, kill a load of people in reprisals for the death of said idiots... then calmly walk away with a land-grab thanks to a "peace treaty".
Others managed to make it work for them... until politics caught up with them in other ways (like, suddenly having a town grow around your mission and the company moving in and shoving you to one side). <shrugs>
If you're telling me that didn't happen at some point out West, I'll start cooking a hat for you to munch on. I can do remarkable things with cumin and a deep fat fryer.
Just because it'd be average, doesn't mean every last person in the time and place was actually doing it. North America is a big place and loads of people settling it back then came from a lot of different cultures: not all would have thrown old principles out for survival's sake, even if it would have been wiser to do so. So finding somebody like Luke? Not all that surprising, really.
Dumb, but not surprising. Kid's learning: it sometimes takes decades to fully adapt to the bush or the outback... if you're lucky enough to survive your dumb phase.
EDIT: When you think about it, a lot of colonial histories and legends are made up of "don't do this dumb thing that this idiot did". Case in point: the short history of the fool who left East London (well, it was Port Rex at the time) with the aim of setting up a farm and taming Cape Buffalo out near the Nahoon somewhere before it was properly settled. They killed him: everybody told him they would. You can't tame Cape Buffalo by any normal means, and they really don't appreciate you trying to corral them.
