What are the chemicals? Can't help my curiosity. Others have said manufacturing quality is better on USA Glocks, evidenced by lack of tooling marks. I have not personally compared any, but I do see tool marks under my Austrian made slide.
If you can get the USA made model $400 less, go for it.
[Edit: dollar value "less".]
