41 COLT

The 41 Long Colt (aka 41 Colt) is not to be confused with the 41 Magnum (although 41 Long Colt ammo is indeed compatible with 41 Magnum revolvers). Most of the folks who look for this ammo want it for their Colt Model 1877 “Thunderbird” revolvers. They have all their work cut out for them, unfortunately, because 41 Long Colt ammo hasn’t been produced in significant quantities since the 1930s.
