The same 45 cal. ammo used in the 45 cal. revolver. This can get confusing, there are very different cartridges that are '.45'. In semi-automatic pistol the most common is .45 ACP. The ACP stands for Automatic Colt Pistol, that is the company that developed the cartridge. But for revolvers, you would more commonly use the .45 LC (Long Colt) which is a longer round. Modern Derringer's are more typically a two barrel gun that shoots the revolver cartridge, at least in .45. There are many types and calibers of Derringers that have been made for a very long time. The best thing is to research the specific model of gun you have and get the manufacturers recommendations for ammunition.
I own oneof these guns and the .45 acp ammo works perfectly in it. The only thing i can think of is a bad barrel. The good thing about these guns is that the barrel is interchangeable with a colt standard 1911.
This is a small pistol, usually one or two shots, which can be easily concealed. It can be any caliber from .22 to .45. The design was first produced by a Philadelphia gunsmith named Deringer in the early 19th century, or so the story goes.
