I would not want to get shot with that. I carried a 2-shot Derringer for a short time. It was 45 Long Colt and the muzzle rise caused it to hit very high at any kind of distance. I went for greater round count after 5 gang-like youths pulled up behind me at an ATM. At the time I had a Colt 380 Ponylite in my pocket and a Glock 30 back in my car. They were arguing about who was going to get me and I grabbed my cash and made it back to my car and Glock 30 before they decided. They then tore out of the parking lot. After that I never thought a self defense encounter was usually a one-on-one deal again.
Ask ANYONE you know that KNOWS guns and ballistics about getting shot at close range with a .22 magnum hollow point and watch their face when they answer. The shock and awe from the first guy shot with the thing and his screaming would see the other four running like hell.
Aw, skip it. What do I know?
