The Fallout games have been rather inconsistent with how they names their weapons. In general, they use a more 'Generic' weapon naming scheme ('10mm Pistol', 'Laser Rifle', 'Minigun', etc), relegating their real-life names or in-universe names ('Colt 6520'/'N99', 'Wattz 2000'/'AER9', 'CZ53'/'M134', etc. respectively) to the in-game item descriptions (Pre-Bethesda) or certain lore terminal entries (post-Bethesda). There are exceptions, however, like the vast majority of weapons in Fallout Tactics, AER14 Prototype from Fallout 3, YCS/186 and LAER from New Vegas and the M79 Grenade Launcher in Fallout 76.

On one hand, using the Generic naming system makes it incredibly easy to know what you're picking up without actually looking at it. A 10mm pistol is obviously a pistol that shoots 10mm rounds, and a laser rifle is obviously a rifle that shoots lasers, and so on.

On the other hand, having their actual names could be incredibly immersive, from a certain point of view. Sure, you could argue that most wastelanders wouldn't know what a random gun they looted would be called, but most guns that I've seen have had some sort of etching or engraving on the side to tell their model and who they were made by.

My question is, which would you prefer them to use exclusively as a standard method? Would you prefer if they used a more simple and useful 'Generic' naming scheme like how they usually do it, or would you prefer the potential extra immersion of having their full in-universe names listed?
