I guess Dan did derail the thread with the rail on a pistol comment, and I didn't help matters, either.
Nonetheless... you guys with the military background know - or should know - that ROE/RUF in a theater are vastly different from a tangle of things that pass for ROE/RUF state-side. They differ state-to-state, and city-to-city. However hideous it may sound, in some places it is "better" to kill than to wound/incapacitate an intruder, in the others - not. There isn't a single weapon or set of accessories that's universally better than the others. In this sense, the guys/gals with CCW permits are more educated in their options than people without those, regardless of their military training or lack of it.
Returning to the original thread Q - it is like "Jeep vs Land Rover" on a general 4x4 BBS. A Grand Cherokee or a Land Cruiser may be a better vehicle overall than a beat-up Discovery, but I like the latter and don't like the former two. I already forgot who mentioned it in this thread - use what fits in your hand better.
