Some of Strucker's henchmen carry Beretta M92FS pistols - 9mm. Notable in one scene, a henchman on the roof carries a Beretta 92FS until he bursts onto the roof, then he is carrying an H&K USP pistol, but the gun changes back to a Beretta 92FS when he fights with Kar (Seann William Scott).
Heckler & Koch USP
One of Strucker's henchman's gun changes to a Heckler & Koch USP on the roof (which is a continuity error, see above).
I think its a USP Compact due to the trigger guard angle.-GunnutHk

GE M134 Minigun
Strucker's men assault the Monk's building with a Helicopter, sporting a GE M134 Minigun as armament. Instead of a 'acetylene' fake Minigun that has been used in other movies, this is a real GE M134 Minigun, as evident by the loads of spent brass and belt segments flowing out of the sides.
