I think the problem is from SetPlayerWeaponEx function, as you said the player lost their weapons when they leave a vehicle.
Maybe, show us SetPlayerWeaponEx() function?
and use pastebin next time if you want to post long code.

if(oldstate == PLAYER_STATE_DRIVER)
{
	if (_vhudVisible[playerid] == 1)
	{
		HideSpeedo(playerid); // incase vehicle despawns
	}
	if (CarRadars[playerid] > 0)
	{
		PlayerTextDrawHide(playerid, _crTextTarget[playerid]);
		PlayerTextDrawHide(playerid, _crTextSpeed[playerid]);
		PlayerTextDrawHide(playerid, _crTickets[playerid]);
		DeletePVar(playerid, "_lastTicketWarning");
	}

	SetPlayerWeaponsEx(playerid);
}
else if(oldstate == PLAYER_STATE_PASSENGER) SetPlayerWeaponsEx(playerid);
