Somehow I doubt the 'sights' argument is helping for_fire find what he needs.
Like they say... practice, practice, and more practice.
After that a hogue forend, and a sidesaddle either on the reciever or the stock or both. There are lot's of different models made by as many makers. I prefer the reciever. Tacstar I believe sells one for around $30-35 which seems pretty solid (I recently got the 6 round one for reciever but havn't tested it yet).
Forget the sights and the light, put a nightlight in every room. At night your eyes will already be adjusted to the dark and you'll be able to see anybody just fine. Make sure you have bright lights always on surrounding your house. The bright lights alone will probably deter most common theives because for one they dont want to be seen by neighbors. Also you'll make any would-be baddies eyes adjust to the bright light. Then if they make it inside, they are basically blinded where it is dimly lit. Game over: You 1, bad guy 0.
In the day time a good shooter with quick feet that knows his bead may be one of the best tactical accessories known to man.
Although you should never really touch the barrel for any reason anyway while at the range, heatshields are nice once you get comfortable and start to shoot alot of watermelons, beer bottles, soda cans and things of that nature. I've put a few singe marks on more then one blanket this way, it just all depends on how you shoot. IF your anything like me you'll find that shooting stuff is fun! Just dont get the cheapo ones, they SUCK! If you absolutely need one then I think mossberg sell the factory heatshields seperately, so check it out. Maybe you already have one in which case forget this last paragraph.
This is all my opinion, don't blame me if blinds pop up and the heatshield flies off the barrel in the middle of night. :banghead:
