Not sure what you mean. Since the bullets in both the .38 special and the 9mm are of the same diameter, the question then becomes, which cartridge would give better performance? In most instances, a hollow point from a 9mm cartridge will expand better than one from a .38 Special.For shooting people (what you'll really need to do when you defend yourself) I would never, ever pick anything smaller than a .38 Special. 9mms are too anemic to put a person down for good with one shot.
I won't argue that the .45 acp or the .357 mag have more than enough power to be effective "man-stoppers" and the .45 colt certainly can be depending on how its loaded. But,I stop short saying that about the .38 Special. Despite all that, what's more important is shot placement.The .45 ACP is a proven manstopper, as are the .38 Special, .357 Magnum and 45 Colt.
Despite my reservations about the .38 Special, I would agree that those are good choices Don't forget too, .38 Special can be fired from a handgun chambered for .357 magnum, though not reverse. One gun, best of both worlds!But, I would recommend to most people a revolver in .38 Special or 357 Magnum.
That about sums it up. It's true that most folks put the .38 Special and the 9mm at the bottom of the list, but on the list. Some go down to the .380; some .380 guys will argue that, with the hottest load, they are more effective than a 2" .38. For some, there's nothing but the 45ACP. But, I also think equipment is the last thing you need to think about. I would say the important things for a self defense scenario, in order are:Having said all that, the most important thing of all is finding a reliable gun that you can shoot well in a caliber that you can manage. Only the gun owner can determine what that is.
I couldn't agree more.Having said all that, the most important thing of all is finding a reliable gun that you can shoot well in a caliber that you can manage. Only the gun owner can determine what that is.
