You can't use OnPlayerTakeDamage() to create lower weapon damages if the player has 40hp and gets shot with a deagle they will die even if the damage is set to 1hp. There is ways to do it however you can create server side damage variables and give the player high health values or use OnPlayerGiveDamage() but if you have lagcomp on OnPlayerTakeDamage() is not the way to go.

All those other responses are from people who have absolutely no clue what they are talking about take it from me you got to do a lot more than what you are doing.
