The 10mm in original format, a 200 gr bullet at 1200 fps is damn near the .41 Mag in terms of power. It's probably more than is needed for most self-defense scenarios. Great for rural or mountain environments where livestock or predators might be a concern, though.
I believe the .41 Mag was originally adopted mostly by rural law enforcement for the same reason.
Predators are a greater risk for suburbia than many realize.
When, in my old neighborhood in CT, a couple dog packs were reported, I decided to carry large.
I didn’t carry large for it’s affect on people, I did it because of pit bulls. Because of course, the dog packs were just pit bulls roaming the streets.
A dog doesn’t know what a gun is. They don’t understand the muzzle or the action of it. They don’t even understand the bang. They are designed for forward motion and nothing will stop that motion until you start breaking the muscles that produce that motion.
People know to fall when they get shot. Dogs have no idea and I’ve seen many cases where a charging pit bull has taken x number of rounds and still charges. You have to actually break the dog so it can’t move forward.
It’s a sad scenario, but it’s reality. I carry large in suburbs and near cities. You know, where “Pitbull americans” congregate.
Out here in the woods, I can carry pretty much anything but I carry a rather remarkable .357 magnum round. IT’s 180 grain, SJHP which is just odd. But it’s case of bears because they don’t know when to stop attacking either. They have no concept of being shot.
I’ve encountered a coyote that I just wanted to go away. I shot at the ground and it did the trick. Bangs make wild animals go away but packs of dogs don’t seem to be effected.
