The oldest argument, Glock? or XD? I say get a 1911a1, for about 90 years the 1911a1 was our millitarys main sidearm (read that again-NINETY YEARS) the Glocks doesn’t have a manual safty,
The XD is NOT manufactured in the USA, Springfield armory imports them,
from the city of Karlovac, Croatia! their made by HS Produkt (formerly I.M. Metal)
Glocks are made all over the place- USA, Uruguay, France, hong kong…
I’d say go with a Springfield armory 1911A1, but they import those from Brazil,
So, if you want a gun that you know beyond a shadow of a doubt that its made in the USA, go with Kel-tec, or kimber, meaby Smith & Wesson.
