Hey, this has turned out to be a pretty informative thread. Thanks for all the info!

JJ, the gun dealer I'm having my guns (I also bought a Glock 21) shipped to has one of those little pump shotguns. It's the 870 version. Two in the mag and one in the pipe, better make 'em count!

I have to say that hearing the sound of a pump shot shotgun being racked is pretty intimidating, but, staring down the barrels of a sbs has it beat!
