Just counting handguns we own: Ruger, Colt, Les Baer, USFA, S&W, Seecamp, Kahr, Kel-tec, North American Arms, and SIG. Yes, SIG, which, depending on the model, has more USA-made parts than many "American" products.
The last Springfield 1911 I owned was assembled in the USA, which does count for something, but the major components were made in Brazil. The XD is definitely of Croatian origin.
I personally own more Rugers and USFAs than anything, and both of these company's current products are 100% made in the USA. USFA did start out using imported parts, but shifted to making their own parts in-house.
To drift into long guns, we have Remington shotguns, and rifles made by Ruger, USRAC/Winchester, Marlin, and my AR is a Colt upper on an S&W lower, with Rock River and JP Enterprises internals.
Our only totally non-USA handgun is a Walther PP. Our only non-USA rifles are Miroku and Rossi lever rifles.
