22 for defense
Warp ......This is for you. You downgrade almost everything anyone has to say. These people are making an effort to find a weapon suitable enough to defend themselves with in their particular situation. We all know nothing is perfect and minimum is just that......minimal but capable. To use some sayings you use for a guide....... "The only thing necessary for evil to triumph is for good men to do nothing."
― Edmund Burke
These people are making an attempt, not just laying back and hoping they won't be a victim !
“In any moment of decision, the best thing you can do is the right thing. The worst thing you can do is nothing."
They certainly don't fall into the doing nothing category ! A 22 will work, 2 would be better. As far as stats go, I doubt you would believe any stats other than what you might find yourself , so do that ? No one is arguing bigger isn't better, but you have to use what you are capable of, no matter if it's just small bore.
PS....A person with a broken elbow or whatever part, realizing it or not, can not use that limb, it has been neutered ......
