The first pistol I bought when I was a teenager back in the early 70's was a replica Colt 1860 Army .44 great fun to shoot. Just used Crisco over the chamber mouths and never had a problem with chain fires. Reasonably accurate, unfortunately it was one of the guns I had to sell to pay for my first English double rifle and never have replaced it. The Colt Navy 1851 was .36 cal but I have seen some replicas in .44 Been thinking about either a 2nd or 3rd model Colt's Dragoon (replica) may have to get one just because.
