I'm a big fan of guns that have been customized for carry and use. I like to see peoples takes on what is needed in a "fighting" gun, whether they're one off guns that someone did themselves or commissioned a 'smith to build for them, or custom shop guns built specifically with carry and defensive use in mind.
I've got a few that I think fall into that "Combat Custom" category -
Colt 1991A1 Compact w/full Clark Custom "Meltdown" package
Detonics CombatMaster customized by Dietrich Gunsmithy
Austin Behlert custom S&W 25-2
Charter Arms/Mag-na-port "Backpacker" .44spl
9mm (9x23) S&W 360J customized by Pinnacle High Performance
S&W PC 586 L-Comp modified and refinished by Dietrich Gunsmithy
S&W 1917/1937 Brazilian, old custom, don't know who did the work
S&W 29-10 Mag-na-port Custom, just bought this one, picking it up later today
