During the insurrection these pistols were pulled from the line and were replaced with the older Colt Model 1873's. Although not as fast to reload the 1873's 45 Long Colt round had unquestionable stopping power that must have made many troops sent there happy.

Yes Anzac these pistols continued in production until 1908 when they were superseded in 1909 by the Colt New Service.

If you ever plan to shoot it never attempt to use a .38 Special as the .38 Long Colt was always a low pressure black powder round. I think a .38 Special will be too long for the cylinder anyway.
Black Hills Ammo loads this round to the original power levels however I don't know if they load it with black or smokeless powder. The round did have a reputation for being accurate in its day. If the bore is in good shape it may be fun to shoot with correct ammo. - Bill
