Indeed, and I've also tiered Gang Weapons to Tier 2.

There's no reason as to why gang or business weapons should be so far above regular weapons that they are in a tier of their own. They should provide members with a mid-grade weapon as a reward for making it into a gang.
That way, you can use the gang weapon as you work to earn a higher tier weapon.

In other words, gang members should have reached the point in the game to possess a Tier 2 weapon (your skill-level should warrant it).

In short, this'll promote gangs even more.
