A lot of people this thing about reloading, but honestly, my reload time after a couple weeks of basic training was under the five seconds you need to pass, and after a couple months of service plenty of people were closer to three seconds. I have a hard time imagining that swapping weapons is quicker. I guess the reloading thing might be the reason to have many guns, but it strikes me as a strange one.
And really, I’m not only talking about this specific case, I get the feeling that people that are into guns will often focus on the number of guns someone has, also outside this case, which seems a bit of a strange metric to be talking about in general.
