No question:
Vash the Stampede's 45LC Top Break Blaster
I'm sure Dirty Harry's Model 29 will rank highly. I think my 8-shot .357 TRR8 looks pretty mean, with its evil matte black finish and faceted shroud. Did I mention it's looks are backed up with 8 rounds of .357?
Weighs as much as a gun half as intimidating, too
