So I got the idea (after re-watching Trigun) to try to play through avoiding killing anything and everything possible, relying almost entirely on speech and outrunning foes. This worked well enough, however there were several notable cases (mostly with Deathclaws and Fire Geckos that aren't affected by things like the Animal Friend perk) that simply had to be killed in many situations, plus there weren't really any guns that could reliably knock foe's health to the point where they'd cower instead of fighting to the death.

This weapon aims to solve that. Thus far it has worked very well in my personal testing and I figured there may be someone else who might like to use it as well. The weapon works as follows:

While it is still a projectile weapon, it's damage is very low. I did manage to add Fatigue damage, however, and properly apply it to everything but robots such that it can knock out almost anything living creature in 1-2 hits. The attack compensation for attacking robots brings the damage up to slightly higher than the hunting pistol (about the same as if the damage was set to 75) and ignores DT/DR. The weapon is also given a considerable - but not perfect - VATS accuracy bonus (on-par with the Anti-materiel Rifle).

Repairs: Same as Hunting Revolver.

The pistol uses 45-70 Gov't ammo to keep the gun true to the .45 caliber of the series, plus makes getting ammo a little more challenging (and, most importantly, it prevents the mod from being dependent on the Honest Hearts DLC for models/ammo/etc.).

The weapon cannot be given mods - same as most Unique weapons.

THE GUN IS GIVEN TO YOU WHEN YOU FIRST LOAD THE MOD ON A SAVE, REGARDLESS OF PROGRESS. You can, however, craft more if you want a spare/lose your first one (WARNING: it's not easy to craft)

Crafting Requirements:
Gunslinger and Jury Rigger perks
Repair skill 65+
1 Hunting revolver, 1 .44 revolver heavy frame, 1 conductor, 1 Pilot light, and 1 "Guns and Bullets" book (skill book not consumed)
