Ehhhh #1 - Just in my lifetime , Colt has had a myriad of corporate ownership . At least now , the corporate parent is primarily firearms focused , and has capital to invest in Colt .
Ehhh #2 - Many/ most ? Of the Service Pistol Suppliers are Foreign owned . Beretta , SIG , Glock are the 3 of the top 4 U.S. LE pistols , and FN would be very pleased to do even more LE business . Our own S&W spent a significant period of years being Foreign own .
Looking from different angle , Glock , SIG , and Beretta have major manufacturing , and R&D operations in the U.S. . Reversing that , Springfield Armory is U.S. owned , but most of their handguns are actually built abroad .
For LE Agencies , what matters is the U.S. based LE Support network , not the location of corporate parent headquarters .
( Ok , probably China or Russia would still generate pushback . But the usual players are just part of the global economy .)
