Last I checked the RIA 1911's are made by Armscor. Now they have their USA headquarters in Parhump, NV. They are making some ammo in Montana and they have plans to open a factory in Parhump to build firearms, but I don't think it is open yet.
The point of this ramble, somewhere back on page 1 someone mentioned American made. Armscor is Phillipine. Not saying that there is anything wrong with that and they are one of the largest firearm manufacturers in the world, just like it understood that modern RIA is not US made. I have seen a lot of new RIA 1911 and have yet to hear anyone unhappy with them.
