Some years ago, I recommended a shotgun as a primary home defense weapon for those who were novices at the shooting sports or the use of firearms for defensive purposes. My recommendation still stands.
I've heard objections from some people over the years that a shotgun - or a rifle, for that matter - is simply too long to use effectively inside a building. "You won't be able to go around corners without exposing yourself!" "A bad guy will simply reach out from cover, grab the muzzle and push it down - then you can't hit him!" My response has always been that with proper training, those aren't problems at all.
Now Clint Smith of Thunder Ranch, whom we've met in these pages before, and with whom I've trained when his establishment was still based in Texas before it moved to Oregon, has produced this video illustrating that a long gun isn't all that long in practice. It's worth watching.
That shows the reality very clearly. A long gun is perfectly adequate for home defense - in fact, more adequate than a handgun, more often than not - if one knows what one's doing. If one doesn't, no firearm will be particularly useful.
