Weapons with a documented provenance will probably never get in my home because market demand will jack up the price too high for me to pay.
A gun used in a suicide? I wouldn't hunt them down, I would take them if offered to remove them from the suffering familiy.
Weapons produced before I could make a cognizant decision about whether slave labor was involved? Old pieces before say, 1971, probably. Current new in the box, what are we supporting? If anything, this discussion has prompted an awareness that I shouldn't buy any new Chinese AK.
On the other hand, I've trained, shot, carried, cleaned, inventoried, and finally. loathed the 1911. Like horses and 55 Chevies, they have become the most admired pet objects in the firearms industry. And like the hotrod industry selling small block chevy parts, the 1911 industry sells all sorts of mods, improvements, and gimmicks to improve the functioning, reliability, and accuracy of what is obviously Brownings's less than perfect design. If it was perfect, we wouldn't bother.
The Hipower is the true Gen 1 of all modern combat pistols - double action, double stacked. The 1911? It has a place as a historic relic, and that's the best can be said for it. Not being available from the DCM is probably the best thing that ever happened - they were sidelined because they were used up junk. The American government doesn't need the liability issues. It's successor - politically appointed as a trade for the use of Italian military bases, is nonetheless a superior duty firearm.
The Beretta 92 can directly trace it's mechanical history to the Walther P38 - a Nazi era weapon. The M60 feed mechanism can directly trace it's origins to the FG42, the Kevalr Helmet can directly trace it's origins to the Stahlhelm. Those mechanical origins have nothing to do with the philosophical mindset of the administration that invented it.
It's an American tradition to absorb the mechanical ingenuity of our defeated opponents. Might be one of the things that keeps us on top. Buying or not buying the relics of past conflict has nothing to do with the object itself, and everything to do with our emotional assessment of it.
If it bothers you, it bothers you. Later in life, it might not. I bought an LCP after Bill Ruger passed on. You can't hold a grudge too long, you might find yourself on the wrong side of it eventually.
