I always seems odd to me that everyone dumps on the Chinese for making crappy stuff. China isn't making crappy stuff because they can't make it any better, they make crappy stuff because that is what we ask them to make. Walmart, Canadian Tire, Home Depot, they specifically contract Chinese companies to make barely acceptable goods for the least amount of money possible. The Chinese will build what they are contracted to build, and that includes the Dollar Store stuff. Odd how everyone dumps on the Chinese for building crappy stuff, yet praises Apple for making the best ###y plastic out there. Where do you think Apple stuff is built?
In regards to revolvers, I agree, they would be a nightmare to build in quantity, just given the amount of craftsmanship that would need to go into each one to make it work well. If anyone could do it, the Chinese probably could. Getting a revolver to work perfectly would require labour and an artisan's touch. China has lots of cheap labour, modern machining, but training someone to have that artisan's touch is not their forte. To do that, you would really want to establish a long-term industry, and that requires long-term demand. It is so much easier to just build a Glock.
