Lets talk about the 4 hour gun limit.
I feel that the 1 gun per 4 hours should be replaced with something of sort like 6 guns per day, as of what you can currently get but at once to make everyone's life easier. 6x4=24, Simple. As of being told by also multiple gun store owners, it is a huge pain in having to buy a gun every 4 hours, especially when you were to forget.
Now that might be the positives, I can see some of you saying the negative would be more guns on the street or something like that, but at this point I don't think we would see a drastic change, as there is still friends always buying each other guns anyways.
EDIT: I want to continue to support this claim, but I feel that we should instead have it where the limit doesn't necessarily change for civilians, but allow gun store owners to buy in bulk of some sort, or maybe they can "order" guns and have a wait time of an hour or some other time before receiving a large quantity of weapons or something along the lines of it. Not only does this bring more interaction for civilians but also allow gun store owners to actually have some other way of having roleplay in their store, other than sitting there for hours while the cash slowly racks up and them struggling to buy a gun every 4 hours for one little sale.
To sum things up, shop owners should be able to buy more guns than a normal person can, to bring more roleplay to the gun store scheme.
