I was given this great pistol two days ago and wanted to get more information about it. It is in great shape and the serial number appears to be 99272. I was told that it was a 32 (1st model) however the latch design on the top leads me to believe that it may be a 38. I would love to fire this weapon but don't know if I should use black powder ammo or not. I guess this is based on the age of the gun. Can anyone help?
