We've talked a lot about gun choice in other threads. This one is about bayonets. So this is primarily about whether or not to add a blade on a gun to augment home defense.
As such, the bayonet can be considered as any long blade, although so far no one has mentioned swords or spears. And like many people, I've always kept a long knife or two handy around the house just in case.
At only 3 feet long and 5 1/2 pounds, the M1 Carbine is quite manageable with a 6 1/2 inch M4 bayonet on it. Still shorter and lighter than many other rifles or shotguns.
So it's doable. And if it came down to a close enough encounter where a bad guy could consider grabbing at a gun barrel, I buy the idea not only that a bayonet would deter or punish any such impulse, but keep harm much farther away than it otherwise might be.

Most replies so far here seem to be No.
Nevertheless, I'm leaving mine on. I'm getting used to it. It's like having one more friend around. I'll never be parading around with it, but it's a comfortable partner in the closet if I ever need it.
