What's the heavyest 9mm handgun out there?

I've shot an X-five, and handled a Steyr GB back in the day. THe Sig is definitely heavier.

The GB may be a contender for the standard gun category though (that's not a converted under-bored .45).

"standard" pistols i agree, STI at 51oz is pretty heavy, i can't think of anything that'd be more than that.

however, if we include anything technically counted as a pistol by the atf that isn't a botique 1 off piece, i'd say some type of full size uzi pistol with a long barrel and solid stock.
