Mark, I wasn't just picking on your post. It was "in general" with the question of locking it.
And, actually you can't use a rifle in Ohio to hunt, but you can use a handgun. So, it's not too uncommon here to find guys who prefer a .357 or .44 magnum for that duty. You can use a 12 gauge for deer here as well. I know guys who use either, or get two tags and use both (one, then the other).
As for defense against animals, it depends on the animal. As I stated, a 44 magnum makes for decent bear "repellant" and is less cumbersome to carry than a 12 gauge pump or a rifle. If you're going hiking and not hunting (in bear country), it makes sense to me to carry a reasonably powerful revolver. But, that's just my opinion, we may not agree.
And I very well know that I can hit things with a revolver. I've got about 10-15,000 rounds of .357 mag "under my belt" in the last couple years. However, it only holds 6 and not 10. (IMG:
