A note regarding Clipsize: Any nonstandard value will NOT be in effect at weapon pickup, which means the client
has to reload once to achieve the modified value. To fix this, add a weapon pickup hook in your plugin (eg "player_use")
and use something like this with a small timer delay of 0.1 seconds or more (dont you love this engine)
