I've been looking at making weapon mods for an 1851 Colt Navy Revolver that will allow the player to use an upgraded conversion cylinder. As in, the only cartridge conversion currently available for that weapon is .38 Long Colt, which is obsolete and only roughly half as powerful as a .357 Magnum. I've been racking my brain to figure out a way to have an upgraded, player-crafted, conversion cylinder mod that will allow the caliber of the weapon to be changed to .357 Magnum. I'm semi-decent to mediocre at scripting, so trying to figure that out on my own would take until Fallout 4 is released. Any pointers?
