OK. So I was just providing MisKelly with some advice on purchasing a shotgun for home defense.
Here's my preference:
Remington 870 Express Magnum pump shotgun with tactical magazine extension
Safety (button behind trigger) Off
00 Buck (5-shells) in the magazine
Hollowpoint slugs in buttstock mounted shotshell carrier (Last round loaded is first to be chambered; I can lead off with a slug if needed)
A tactical light with pressure switch (I prefer SureFire as a brand. I don't currently mount one though. The max range in my apartment is 6-10 feet.)
Mossbergs have their safety located on top of the backstrap. I have experienced them working loose during a firing string and reapplying themselves in the middle of a string. In other words, you may be in the middle of firing more than one round and the safety may suddenly activate--this prevents you from firing...can you say 12 gauge club?
I have also used the Winchester and i don't recall any particular foibles. I think they're probably as reliable as the Remington.
Wear these: Peltor (click on Tactical Headsets)
Although I said in MissKelly's comments that these will protect your hearing (and they will) the real reason is so you don't flinch when the gun goes off, causing you to miss your target and kill your waterbed.
Shoot often and straight.
