Are you really that naive? My guess is no you're not, you just own a Sig, and you fanboy out over the product. If the government only bought JD tractors is it because they're just so good that Kubota, NH, CIH, MF, etc cannot compete, or are other factors involved? If the government only bought F150's is it because GM, Ram, Toyota, can't compete with how good a F150 is? Do you really think that Glock, FN, Beretta, CZ, S&W, Springfield, Walther, HK, etc make inferior pistols that can't compete with SIG's? Look there are some SIG's that I like a lot, but since you want to talk pistols the P320 is not one of those SIG's, and it's had more teething issues then the other pistols it beat in the Army's XM17 competition. But that's just one thing. SIG keeps getting fed all these rifle, and ammunition contracts as well, and I believe optics now, etc. You need to spread out the wealth. The government just keeps feeding this one firearms manufacturer, and it's like they're trying to make them into this monopoly in that arena. That's not good, because then you get things like Google who has no real competition and can make their own terms, but who out there can challenge them?
IMHO them building in a New England union state to compete with other firearms companies who our government more traditionally bought from, and who was more established in the U.S. was done for political reasons, and other firearms manufacturers had started moving out the union states, and your largest government firearms suppliers were in the south. FN for example.
