Most of mine are US made. Some of the more interesting ones are not. Made in the USA does not mean every part was made here, all the metal was mined and rifned here, or that all the technolkogy that went into the gun came from US citizens.
I buy the best product at the best pricepoint for my purposes. If you save a few dollars for buying one product over another, then so be it. Over the long run, your saved money will be spent on other consumer goods which will still vitalize the economy. In the case of firearms, you'll probably be spending the saved money on cleaning supplies and ammo from your local sporting goods store. This anti-China, anti-this, anti-that attitude is reminiscent of the anti-Russian attitudes decades ago except Russia didn't have goods to offer. It's silly and childish.
Go blame overinflated unions for squeezing corporations until they go broke and passing on increased cost to the consumer, and Walmart protestors that cry $8-10/hr for Walmart employees is highway robbery when the national minimum wage is lower, and that many non-corporation sized companies pay much less for entry-level jobs (but they aren't evil, so no one complains there)
I really wish the "buy American" blowhards would dry up already - it's just feel-good chest thumping in today's world.
