My interest in certain foreign-made firearms has more to do with their quality. I like CZs, Berettas, older Walthers, etc. I prefer metal, hammer-fired pistols to the modern polymer, stricker-fired pistols.
Some of these foreign nations have gun laws that are what we in the "free" states might call restrictive. Their laws may grant (not insure) some degree of freedom with regard to firearm ownership, but not like we in the "free" states have. Somebody chime in if they know better, but as far as I know the natural rights insured by the Second Amendment are unique to the United States. I can think of another country that might have something somewhat similar, but I have not researched it (some of our Swiss members chime in).
Smith & Wesson is in the process of moving its HQ and much of its manufacturng to Tennessee, although my understanding is that its revolvers will still be manufactured in Massatuchetts.
My understanding is that Ruger, while headquartered Connecticutt, also manufactures firearms in Arizona, North Carolina, and New Hampshire, none of which I would consider to be rabidly anti-gun states (e.g., New Jersey and California, etc.).
Others can chime in with other examples.
Should the question be the State where the firearms are manufactured, versus where the company is headquartered? I don't know.
By "free" states, I am referring to those states that have far less restrictive gun laws and have placed the rights insured (not granted) by the second amendment in their State constitutions.
I don't know of any firearms manufactured in California or New Jersey, which again, I consider to be among the worst.
I made a distinction between "insure" and "granted" since I believe the Second Amendment does not grant, but rather recognizes and insures our natural rights to keep and bear arms.
I am not sure how relevant all this is to original post, but these are thoughts I had after reading it.
