I buy what ever appeals to me, without regard to country of origin. I snapped up a Norinco 1911 in the 80’s when they first came out. Got a MAK 90 back then too. When all the PD’s were buying Beretta 92’s, I got my first Taurus, a PT-99, because of the frame mounted safety, I was very accustomed to 1911’s and the slide mounted safeties or decockers just seemed weird to me.
More recently, I bought a Canik TP9sfx that I saw in a store case, on sale, knew nothing about Canik, hadn’t even heard of them, but I thought it was a cool pistol. It is the most accurate 9mm that I own.
The worst gun I ever bought was a Parker 1911, made in USA, and a total POS, literally a paper weight. I owned long enough to drive home, tried to shoot it, drove back to the shop and returned it. All in the space of about an hour.
Not to mention all the military surplus arms from other countries I’ve had.
I do believe that the United States produces many of the best firearms in the world and I have or had a bunch of them, but country of origin is way down on my list when shopping for guns.
