📋 About This Mod

Various replacers exist on the Nexus but many do so by model swapping. This can cause many issues (some of which I encountered).

My replacer(s) work much more simply by changing the level lists, allowing for easy conflict resolution through changing load order to ensure this mod over writes and mod which changes LLs.

This mod should hopefully demonstrate the huge advantage this approach has, yes, multiple weapons replacing one weapon.

Replacing the 10mm pistol with the N99 10mm, the colt 6520, glock19x, hkusp9mm, HRP_mk23, p220.

I recommend this mod for the p220

The 9mm pistol mod is needed for the light and lore patch due to all pistol cartridge conversions being converted to their IRL counter parts (aka 9mm). This also gets rid of the "ammo" type gun mods use, primarily in preparation for any mods that add true ammo types.

Included a patch for ECO to ensure the guns are made.

For this to work fully a new game is needed.

While it partially works without a new game, as all new 10mm pistols found will be one of these, all existing10mm pistols remain untouched.

🤖 AI-enhanced — based on mod data

This Fallout 4 mod replaces the standard 10mm pistol with six real-world handguns: the N99 10mm, Colt 6520, Glock 19X, HK USP 9mm, HRP MK23, and P220. It's a straightforward cosmetic swap for players who want more realistic firearm variety in the game.

⚠️ Cons

  • Last updated in late 2022, so it might be stale for newer game patches
  • No mention of compatibility with other weapon mods, so conflicts are possible

💡 Beginner Tips

  • Make sure to place this mod after any other weapon mods in your load order to ensure the replacer takes effect.
  • If you use a mod manager, preview the weapon models in-game to see which one you like best before committing.
  • Since it's a replacer, it won't add new weapons to loot—just changes the look of the existing 10mm.
