MAC-10

Unpack the archive and move the .mdl files into your game directory. When swapping out the MAC-10, you'll typically find v_mac10.mdl (first-person view), p_mac10.mdl (player model) and w_mac10.mdl (world model). Place them in cstrike/models and agree to overwrite. If your installation uses a localized folder, go with cstrike_russian/models instead.

Weapon models belong in the models directory within your game folder. The usual location is cstrike/models. For a localized build, cstrike_russian/models is used first. Any custom sounds bundled with the model belong in cstrike/sound/weapons.

First make copies of the original v_mac10.mdl, p_mac10.mdl and w_mac10.mdl from cstrike/models. After that, move the new model files into that same directory and confirm the overwrite. Reload the game or switch maps to load the new model.

• Verify the files sit in cstrike/models or cstrike_russian/models.
• Confirm the file names line up with the originals: v_mac10.mdl, p_mac10.mdl, w_mac10.mdl.
• Should the model still be missing, the archive might hold a different weapon name; rename the files so they match the MAC-10.

Remove the custom v_mac10.mdl, p_mac10.mdl and w_mac10.mdl from cstrike/models. After that, check your game files via Steam or restore the originals from a backup. The stock model will load once more.

Custom models are client-side on most servers and function without issue. That said, certain servers enforce consistency and might swap your model for the server's version or disconnect you when files don't match. If you're kicked, delete the custom model or join a server that permits custom content.

Custom sounds shipped with a MAC-10 model typically belong in cstrike/sound/weapons. Keep the original file names so the game can locate them. Should the sound fail to play, confirm the file format is supported and the path lines up with the one in the model's qc or the game's sound folder.
