G3SG1

1. Unpack the downloaded archive and check its folder layout - it typically matches the game's folders.
2. Place the .mdl files into cstrike/models, overwriting the existing files when prompted.
3. Put any custom sounds into cstrike/sound/weapons, preserving the original subfolder names.
4. Launch the game and pick the G3SG1 in a match to verify the new model appears.

Before copying anything, make backup copies of the files you will replace.

Weapon models belong in cstrike/models: v_g3sg1.mdl is the first-person view, p_g3sg1.mdl is the weapon in the player's hands, and w_g3sg1.mdl is the weapon on the ground. Sounds go into cstrike/sound/weapons, while sprites or HUD elements go into cstrike/sprites.

If your game includes a cstrike_russian folder, keep in mind that files there override those in cstrike, so check both locations.

First, back up the original v_g3sg1.mdl, p_g3sg1.mdl and w_g3sg1.mdl from cstrike/models. Then copy the custom files with the same names into cstrike/models and confirm the overwrite. If the archive only contains v_ and p_ files, the weapon on the ground will keep its default appearance.

• Verify that the files are in cstrike/models and not in a nested folder like models/models.
• Ensure the file names match the originals exactly, for example v_g3sg1.mdl.
• If a cstrike_russian folder exists, the same files may need to be replaced there as well.
• A corrupt or incomplete download is a common cause of crashes - re-extract the archive.

Restart the game after copying files so the new models are loaded.

Delete or rename the custom v_g3sg1.mdl, p_g3sg1.mdl and w_g3sg1.mdl in cstrike/models, then restore your backup copies. The same goes for any custom sounds in cstrike/sound/weapons. After restoring the files, restart the game.

Custom models are client-side visuals, so only you see them, and the server determines how the weapon actually behaves. Some servers replace models with their own files or kick players when files do not match (consistency check). A model swap never changes damage or real hitboxes, as those are handled by the server.

A full weapon replacement usually includes v_g3sg1.mdl for the first-person view, p_g3sg1.mdl for the player's hands, and w_g3sg1.mdl for the model on the ground. Optional files are custom sounds in cstrike/sound/weapons and sprites in cstrike/sprites. If the archive contains fewer files, only those parts of the weapon are replaced.
