What guns do SWAT carry?

probably the MP5, M870 and the pistol. dunno what pistol though. I'm also not quite sure bout' the M870 too. But the MP5 is definite.

Added: I'm sure the first answer is probably correct for the department or agency the writer is famiar with - however the equipment used and carried by SWAT teams can vary greatly from department to department, agency to agency, and state to state.
