Then script it....

pawn Код:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate==PLAYER_STATE_PASSENGER)
    {
        new gun,tmp;
        GetPlayerWeaponData(playerid,4,gun,tmp);
        #pragma unused tmp
        if(gun)SetPlayerArmedWeapon(playerid,gun);
        else SetPlayerArmedWeapon(playerid,0);
    }
    return 1;
}

This forces player to use an SMG, Tec9, or Uzi only if they have one, otherwise sets their weapon to fists.
Tested, works great.
