I'd be ok with this if we had to like, regularly maintain them at risk of losing them for example, but idk. I don't really see guns as 'ineffective', the fact that they draw a crowd is one of the very things that makes them appealling, you can essentially relocate the area's entire population into a concentrated sector and either come back to chip off numbers of just ignore it. And now since guns ALWAYS hit, even if they don't deal dmg, you can just go hog wild.
I'm ok with this, but I don't think guns need the help
Well this isn't necessarily true. With enough money collectors can acquire illegal goods w/ ease, and there's zero doubt some departments "lost" a few shipments of G18s once they realized how worthless they were for their intended role. You can find bone stock, full-auto capable G18s on the street for a relatively small upcharge compared to any other glock with a switch. You pay extra for the name, essentially
Still seems like a very strange pick for this kind of game, though
