I really like the PJAR Pistol by lucasncolombo. The animation is unique, the makeshift style is beautiful and fits right in the Fallout aesthetic.
This is why I decided to make some tweaks for it and try my best to impletement it in the game as if it was originally part of it.
This is part of a bigger effort to immersively bring more gun diversity into the Commonwealth and enrich the experience that Bethesda planned for this game. Check my profile for more.

LOAD ORDER after PJARPistol.esp

LEVELED LIST
Using Dank's Leveled List Injector, I placed the weapon in most places where 10mm Pistol spawns but 1-2 levels sooner.
New LL Change that does not follow the 10mm example - I placed the gun in the citizen weapon spawnlist since they only had Pipe weapons. PJAR fits this makeshift category and they need diversity in the weapon spawns.


STATS
Balanced Damage, DPS, weight, value, AP cost to make it perform similarly to 10mm Pistol but a bit worse. DPS sits between Pipe Pistol and 10mm.


CRAFTING
WEAPON MODIFICATIONS
Stat modifiers from receivers, magazines etc rebalanced to roughly give the same bonuses as the 10mm Pistol modifications
Modifications will have spawn levels similar to the modifications from 10mm Pistol but 1-2 levels sooner/later
(For example, 10mm will start spawning with POWERFUL RECEIVER at level 10. PJAR Pistol will start spawning with the same modification at level 9.
Added mod collections - this will allow the weapon spawn with random modifications every time, everywhere
CRAFTING COMPONENTS
Added different crafting components/perk requirements to weapon modifications that lacked them/adjusted them to make sense with the corresponding modification
Removed Weapon Recipe from Chem workbench


NAMING CONVENTION
Weapon renamed to Makeshift Pistol
Modifications, loose mods and most things renamed to match Bethesda's naming convention to the best of my abilities


NOTES
The magazine that lets you craft the PJAR Pistol has been renamed to Wastelander's Notes and doesn't grant you the ability to craft it anymore
But I really liked the art on it so I let it be, gave it a better description. Maybe you want to showcase it in a magazine rack in your settlement.

I restructured the No Material Swap categories, renamed the Grip Wraps and Receiver materials to be more lore friendly.


ANY OTHER PROBLEMS?
3rd Person PA Anims: worked well for as long as I tested it. I couldn't fix that anyway if it existed. But it's a good thing to let you know the state of it.
Works with Pistol Perk: yes.
Haven't noticed anything else. Let me know if I missed something. I may or may not be able to fix it.

Also if anyone is wondering, it's perfectly fine to overwrite Dank_GunLLinject.psc and Dank_GunLLinject.pex if you have other mods that use those files. They are the script that does the leveled list injection and it's the same exact script that has to be included in every mod to make sure you have those files in your directory.
