Hello New Vegas community!
Basically what the title says, a 10mm replacer mod that changes its model and mods to be the ones from Fallout 4's "Tunnel Snakes Rule!" CC. I find myself somewhat disappointed with the existing 6520s on the Nexus - most lack the revolving cyllinder, one has a straight up revolver backside, and another has a weird top-only slide (plus overtly smooth normals).
I'm not sure what the legality of doing so would be, but I assume it to be the same as other Fallout 4 -> NV mods, like the PA footsteps mods you can find here and there, or the Combat Rifle backport, or the numerous FO4 PA model backports. Would have to check specific licenses for CC stuff, something I can't personally do at the moment (out of money for Game Pass this month : P).
But that's basically it. Sounds don't even need to be changed, though if one wants to do so, I'd prefer the actual Fallout 1/2 10mm pistol shooting sounds if possible. Distant fire, reload, etc, whatever don't really need changing. Even animations can remain the same, so long as the gun is scaled and rigged appropriately.
Cheers!
