This is turning into a "best HD firearm" thread, but...
If I go carbine, I'd like to go suppressed and/or SBR. However, being in the military, I'm afraid I'd move to state where one or both of those are not an option. (I'm thinking DDM4, fixed BUIS, lower 1/3 co-witness with Aimpoint PRO at this point.)
If I go shotgun, I'd go 870 with a SureFire forward grip. Maybe 20 gauge so my wife could shoot it. Ghost ring sights? Slugs/buckshot?
If I go pistol, I'd go Glock 19 with SureFire X300 or Glock GTL.
Thoughts?
ETA: Eventually, I'll probably wind up with all three.
