Alright, let me just list out some things.
+ More weapon variety, we need some new guns and would be awesome to see some new ones.
- I don't see why this exactly NEEDS to be added to the Civilian class. The Civ class can't mug, rob, etc. Mabye make this avaible for gun dealers to sell. Not so much as a spawner weapon for Civs.
In All: I feel these guns could be neat and used in a way that would benefit. However I don't think giving them to the Civ class will benefit in any way. Sure mabye giving gun dealer /adv dealer these could be useful. I also feel mabye updating the gun class, and whats legal and isn't could be updated.
