The Founding Fathers would not have allowed home inspections of firearms.
Yet wrote and passed the Alien And Sedition Acts. Owned slaves, and did other things that he modern revisionists ignore when quoting WWtFFD
No, I'm not ignoring any of that. Just pointing out that with respect to the OP of this thread which remarked about having people inspect the safety of the firearms (f.e kept in safe, trigger locks, etc) that that would have never flown with those who wrote the Consistitution - namely because they did have to live with some of that under the English Rule where soldiers could decide that you or your property needed to be searched for whatever reason they came up with. This is explicitly why we have the 4th Amendment (no Warrantless Searches) and limits on Property Seizure.
It was a civic duty to have a firearm to start with as that qualified you to be part of the militia (even if you didn't have a firearm you could still join, but then you had to find someone to give you one).
I've never seen that requirement in the definition of "militia". And your wording is odd. You must either have a firearm or have a firearm (by gift/loan) to join the militia. Seems it would be easier to say "must have a firearm to be a member of the militia." Though the current definition has no relationship to armament. And it's impossible to find a good 1776 definition, as they are all tainted by the modern gun rights war (one way or the other).
Look at how people fought at that time. If someone wanted to join in, they had to be able to fight. That typically meant they had to bring their own weapons - the military generally did not provide one for them. This was true even in the Civil War, though by that point the military did start providing some as there was more funding towards it. If you didn't have one, then you had to "borrow" one from someone else who had more than one available.
If you could't fight, or couldn't arm yourself appropriately then you were of little to no use in the militia; though you might have gotten deployed for recon, scouting, or other intelligence operations.
