Got this collectors grade 41 cal colt thunderer today,,all original including the nickel finish,,it was a bit pricey but I had to have it,,,these model 1877s were made in three calibres 38 lightning,,,32 rainmaker,,and 41 thunderer,,john wesley hardin carried a thunderer,,so did billy the kid,,doc holliday carried two lightnings in shoulder holsters,,colt produced a lesser amount of rainmakers making them hard to find today.
