Weapon problem with DarkRP server

[UrbanMyth]

Hey everybody. I'm pretty new to the hole DarkRP side of Gmod, but have learned a couple of things by reading around.

My main problem i can't see to fix (and yes, i have tried to search for a solution) is that when i started out with a fresh install of DarkRP everyone could buy pistols, even the citizens.

I want it to be so that only the gundealers, and future blackmarketdealers can buys these weapons.

The things that i have tried is.
- Set the m.Config.restrictbuypistols to true
- changed every weapon to a custom shipment (Put the code in the darkrpmodification-master addon)
The thing that happened when i did this was that, now the citizens could not buy the weapons, but the weapon tab(not the shipment) disappeared from the f4 menu.
And when i tried another custom shipment code, the weapons where put in the shipment tab regardless if i put them as a shipment or single gun.

Here is the code u currently use:

AddCustomShipment("Desert eagle", {
model = "models/weapons/w_pist_deagle.mdl",
entity = "weapon_deagle2",
price = 215,
amount = 10,
separate = true,
pricesep = 215,
noship = true,
allowed = {TEAM_GUN}
})

I would greatly appreciate every bit of help anyone could throw my way. Thanks in advance.
