Fired at "patrol gun" distance there is no practical accuracy advantage of the AR platform over the SIG.
My AR is more accurate then my 556, but my 556 is very picky on bullet weights and styles.
You make a good case...the same in fact my cop buddy makes who is issued an M&P carbine...BUT, for SHTF, I mean total war and in the woods for 2yrs...certainly you'd stake your life on a piston gun?
Uhhh, no? You do realise that thousands and thousands of soldiers and cops use DI guns every day right? I'd be happy with a high quality version of either, it's simply not that critical. It's the indian, far more then the arrow bud.
I "like" a Sig P226 better than a Glock 17...but i choose Glock due to its reliability potential under neglect...like you say, we will probably never be in a situation to push a semi-auto AR carbine or a Sig P226 to failure...but "just in case" I like the idea of the more reliable weapon.
I've got both, and both are exellently reliable pistols. I think you're overly concerned about reliability in an almost OCD like manner. I find it just a little bit rediculous that someone would NOT carry a sig because they're worried about "reliability" :p.
Also, the heaviness up front makes for less barrel rise
It helps to put down your purse when you shoot man :)
; especially if you are talking full-auto...the Sig 516 (or something like it) is what our military should be issued in place of the M4...Let the SWAT teams keep carrying the DI guns. In fact, Senator Coburn is trying to get a bill through to dump the out-dated M4...I think MANY people in decision making positions know there is a problem but they do not have the expertise to know the mechanical differences and advantages/disadvantages of DI vs piston guns...My cop buddy became defensive when I questioned DI, but he doesn't know what DI even is...he was defending the AR15, bot the gas system LOL...I sent him a pic of my 516 and he siad it was a nice AR...the fact it is piston did not register with him LOL...I think this is true for 80% of people who own and discuss black rifles.
Opinions, opinions :p. Yeah, and you seem to have already decided what's best for the military and pllice despite being neither :).
I'm glad you like piston guns, nothing wrong with piston guns. Just don't let an unreasonable complex about absolute reliability blind you to practical realities. Real life has a way of trumping theory, and real life will tell you that the gear you're obsessing over just isn't as critical as you seem to think :).
