Thanks, Black Bear!
I really appreciate your guidance. I live in a more urban environment (suburbs) than you so my requirements for HD are a bit different from yours. My indoor field of fire is 25' max and my backyard maybe 45'. I have an 870 equipped with a Surefire and a Kimber Ultra Carry which is also my carry weapon. Based on what you say, the 870 will be upgraded with a laser. I also have an office upstairs that is separate from the main living quarters, again with a 25' max FOF. It overlooks the living area below and so is good vantage point. I work up there at night a lot so I just bought a Hi-point 9mm carbine which is coming this Friday. I have a laser/light combo to put on it and will keep it in the office. BTW, I live a mile from a beautiful indoor range and practice with all the weapons once a week.
