With a blade front sight I'd be lookin' mighty close for a shortened barrel... Shorter brl lengths are rarer, but not cut lengths.

IIRC, True .32-44 ammo had a wadcutter style load with the case nearly as long as the chamber and a flush seated bullet. I looked for my small cache of genuine cartridges the other day but didn't locate them... I'll take another look as this is bound to come up again.

After seeing .32-44 listed with .32 Long as that cowboy ammo, just for grits and shins I dropped a .32 S&W in the chamber of my .32-44 and it rattled around... No interchangeability there, so none for .32 S&W Long either...

NM#3's are dandy revolvers and I did a custom project with one and a companion Marlin M-94 both in .44-40 several years ago. The revolver started as a .38-44 target with the longer cylinder. I think there are a few pix on my web site in the Lever Action stuff?
