Well, I still cannot see the misinterpretation of the post, I will however assume responsibility for posting poorly.
I would assume, hate that word, that if one were to have a firearm in a house, rifle, cannon or otherwise, he/she would use such in a pinch. The question was "if" other than in a home situation what would be good--knowin that such would/could be used "in the home-in a pinch".
Lordy I feels like a lawyer trying to dot the T's and cross the I's.
Yes, I know I got it backward, just did it fer fun.
Blessings
