[Bubba in c.a.]

From data I've read, almost all shootouts are at 0 to 20 feet (that's feet, not yards) and that police studies show that cops miss 80% of the time...

So, at 10 meters the average home defender will probably miss almost all the time!

My solution is to train at 0-20feet and concentrate on getting the first good hit with buckshot.

Anything you shoot that goes thru a wall or out a door or window is a hazard to the public. There is really nothing you can do to minimize this other than hit the BG soon with something that will stop him.

Pistol caliber carbines, like any gun, are better than nothing. I sold all of mine when I figured out that nothing beats a shotgun a close range and nothing beats a real carbine at medium range. Pistol caliber carbines are a needless compromise.
