Check out Mark shooting a Bond Arms .44 Mag 3" Derringer with hot hand loads. This thing felt like you hit your hand with a hammer!

I didnt think it was a derringer at first, ive never seen one in .44mag. That looks like it would try to exit your hand if you werent gripping it right.
Well, if you ever DO see one in .44 mag, don't offer to shoot it. There's a reason you don't see these in .44 mag. lol
The tiny grip only allows you to get your middle and ring fingers on it. I was wearing a PACT impact glove which made it even tougher to grip, and even with an impact glove it felt like getting hit with a hammer!
