Troubleshooting1. Place the replacer esp(s) lower or last in your load order. It's possible you have another mod activated that is overwriting the replacer data or your mod manager is auto sorting the esp's in a poor configuration2. If an NPC/Companion weapon is broken, you can individually update them by entering the console, selecting the NPC, and entering the "Resurrect" console command. You will have to do this one-by-one for each NPC. If the NPC/Companion isn't equipping their replaced weapon after the resurrect command, open the console, select them, then enter the "openactorcontainer 1" console command. You can use this console command to view their inventory and force them to equip their replaced weapon and ammo or force them to equip another weapon altogether
3. Take the replaced weapon to a weapon workbench and re-craft the weapon parts. Crafting

✨ Key Features
📊 Pros & Cons
✅ Pros
- Solid community approval (431 endorsements) shows it works well for many players
- Frequent updates (last January 2026) mean it's likely compatible with current game versions
- Simple concept: swap vanilla guns for a sleek modern pistol
⚠️ Cons
- Purely cosmetic – no new stats or gameplay changes, so if you want a functional upgrade, this isn't it
- Requires the separate Walther P99 weapon mod, so you'll need to install that first
For players who want a modern pistol look without overhauling the whole weapon system. If you're tired of the vanilla sidearms and want something sleek, this is a quick fix. Skip if you're looking for new mechanics or stats – this is purely visual.
