For good or ill, revolvers are on the wane. They were replaced as duty/service guns wholesale in the 1980s, and their strongest holdout niche, the 5-shot concealable snubby, is being eclipsed by the tiny pocket .380 pistol.
And it's not like Millennials are going to develop a sudden affection for revolvers (or 1911s) when they turn 40, either, any more than they're likely to suddenly develop an interest in Harleys with their first gray hair.
Elsewhere I predicted that in ten years the shrunken revolver market would be mostly big hunting magnums, weirdo .410 shot pistols, cowboy repros for SASS, and maybe a tiny niche holdout remnant of small and medium frame wheelguns.
