You can change guns so fast, or reload at speeds; by enabling the fast weapon switching it is easy to do, follow the simple steps below

Open Counter Strike, and preferably be connected to a server so that you can test it.

Open the console. This is typically done by pressing the tilde (~) key on the keyboard.

Once the console is open, type in hud_fastswitch “1” with or without the quotes, either way it should work. Press enter to accept. It is now setup.

Test it by pressing 1 and then 2 and then back to 1 – if it switches immediately then it is enabled. If not, go back, and try it without the quotes.

Note

• If you have more than one grenade type, then pressing 4 will not auto switch to the grenade – you will still need to confirm and select which one you want manually.
• In Counter Strike Source, this option can be checked under the advanced options in the keyboard configuration menu.
