Actually, I do consider my revolvers "get out of trouble" weapons.
If I ever need a "fighting gun" and "sustained fire as the round [count] increases" than what I probably really need is an infantry division, not a handgun and a case of ammo. But then I try not to hang around in places where that's likely to become a necessity.
That said, I haven't had a lot of issues with revolver reliability. One GP100 that locked up when barely out of the box, one of the the plunger-spring sets at the front of the cylinder apparently hadn't been set just right at the factory; disassemble, clean, reassemble and no more issues over several years (aka always test thoroughly before using anything new for real). A couple of screws on 40-year old well worn K-frames that needed a squirt of blue loktite to always stay put. That's it.
And I'll second what Darryl said, I don't remember a whole lot of problems at the first revolver roundup, have seen more malfunctions at more than a few training events dominated by plastic semi-autos.
