Many of you might have watched the hltv demos (.dem files) of many professional teams and may have liked the way the weapon switching looks in htlv videos. Well if you did enjoy that and would want to have those models while you play counter strike 1.6 then you can download those models from the following link.

After you have downloaded the models perform the following steps:-
  • Backup the cstrike/models directory to some other location in case that you might want to revert to the older weapon models.
  • Extract the weapon models into the cstrike/models directory.
  • Launch the game and try out the new weapon models.

The following is the video made by someone else which shows how these models look like in game.
