Make it so the really expensive guns that are powerful are hard to upkeep, and expensive to repair. And the cheap guns are relatively easy to upkeep so poor players can not be crippled just because they don't have a lot of money. Create gun licenses for low-damage, medium-damage, high-damage, and ultra-damage guns that you have to renew every so often? This way a bunch of powerful guns aren't always on the street and it's making so the rich people have to spend money to have those powerful weapons. You could also probably put some kind of tax on the licenses for events.
