Does it need to be a Philadelphia Derringer?
I ask as they are rather pricey.
They shoot as well as any other derringer. They are designed for
"up close and personal combat"... OR
"Look, I brought a gun to our knife fight" situations.
So they are meant for targets at about seven feet away.
This guy uses a mallet to load, so he's not using the right patched ball combo (imho)
Shooting Philadelphia Derringer
NO Idea why he doesn't show his target, or even if he hit it.
Now IF you wanted the best "option" for the time period, and you had a choice, the Liegi pistol would be better (imho). In fact you'd want
a brace of them [2]. and a good fighting knife, for EDC. The screw-barrel meant that the bullet was forced onto the rifling, and that friction built up a little better pressure than you get from an equal load in the Philadelphia Derringer. So the ball would hit harder, hence they were very well liked as SD hideout guns.
Shooting the Liegi
Different guy from the first video, but he too doesn't show the target, IF he had one.
The great thing too is that they are available in KIT form from Dixie Gun Works and a brace of them will cost you less than a Philadelphia.... and they are "in stock" right now, another plus in this post COVID time....

I hope this helps. OH Dixie also offers the Philadelphia as a kit.
