If you’re set on getting a .32 Long Colt, I’d suggest looking for an older Colt New Line or a vintage revolver from the early 1900s instead of counting on Rossi to have one. I’ve spotted a few online listings where people claim to own a Rossi in .32 Long Colt, but I’d be a bit skeptical until I could verify it myself. It could just be a mix-up with the labeling.
