Gun-smyth
"I could've been an architect, an engineer, a doctor, but no. I'm here selling mechanized disarticulation to roving killers. Mother would be so proud."

Gun-smyths are Necromunda Underhive Traders, who offer ranged weapons for sell and they can be hired by Gangs for their services. Gun-smyths form part of the Wheeler Dealers group.
Overview
Gun-smyths should not be confused with an Ammo-Jack. Ammo-Jacks are only in charge in selling ammunition and maintaining weapons. Gun-smyths on the other hand, just goes straight to the trigger and sell guns ranging from a simple Stub Gun all the way to a goddamn Lascannon. It is in their name.
Because of their profession, Gun-smyths are one of the most sought after vendors in Necromunda, as without them, a gang will simply just die. So they are often in tough competition with Ammo-Jacks as they are considered the lifeblood of many gangers in Necromunda. They also have one of the most secure jobs due to being... you know... stock full of guns.
For self-defense, a typical Gun-smyth is armed with a Bolt Pistol, Stub Pistol, a Combat Shotgun and a bloody Heavy Bolter.
Crunch
On Necromunda, you can hire one as a Hanger-on for your gang, depending on what you need most in your campaign. Having them around gives your gangers access to an array of naughty merchandise. Crucially, these traders have the ability to source goods that are more elusive.
