I'd like it to be the following:
(1) 12 gauge (this is 'the' standard, no?)
(2) semi-auto
(3) generally black or neutral in color (i.e. not camo)
(4) I'm only likely to buy ONE of these anytime in the near future, so spending $700-$1400 is not a problem
(1) simple range practice (provide Cabelas or MidwayUSA link if possible so that there's no misunderstanding)
For home defense and maximum loads, any recommendation will do nothing more than generate controversy. There are typically several active threads devoted to this subject.
Trap, 3 dram equivalent 1-1/8 oz of # 7-1/2 shot, or
Skeet, 3 dram equivalent 1-1/8 oz of # 9 shot
Both of these loads deliver at 1,200 fps.
That's okay... I'm not sure a 4 foot+ gun is too practical for my home setup anyway. I have a nice selection of handguns (with lasergrips) to pick from for that task anyway.
