Jeff & Peter's Logistical Improvements

It was a boring day in Jugust, everything is normal, even by midworld standard. Joe "Grizzly" Johnson sat on the old patchleather sofa, trying to figure out a way for all the different ammunition used by his steamworld-tech colony. With all the different calibers, shits have gone south multiple times, one day it's the machinegunner lacking ammo, the other day is the rifleman with his bolt-action. Suddenly, the expensive TV on the wall, a purchase after last year's harvest, dragged him back into reality.
"Good morning fellow rim citizens! As general John J. Pershing once said: "tactic wins battles, logistics wins wars" Dug from the history in the 1900s Terra, these old but formidable weapons are added to simplify your caliber choice for technologically disadvataged colonies. From defending your colony, to starting a rim world war. Um, I...I don't really mean that. You know, I mean you can defend your colony through both passive and "active" means. Anyway, hotline number 123-525-3228, hope you'll enjoy!"
Joe stood from the sofa, it's not really that interesting, but maybe it can offer him a way out of the logistical quagmire. He walked to the comms console on the edge of the room, dialed in the number using the numerical pad, and a voice came out:
"Good morning! Or evening or night! I'm mini-Jeff, the digital sales-rep responsible for this brand-new reintroduction of the old Jeff & Peter historical weapons. To simplify the supply chain, Stechkins are removed, but we've added new weapons including the Sten gun and the venerable Browning Hi-Power, as well as minor improvements on the weapon textures. Here's the list of firearms" A list of weapons are displayed on the screen, before the voice came back again.
