I'm not a fan, out of the ones I see they are junk.
The son of a guy I work with picked up one, it was jammomatic and the trigger was horrible. He took it to a 1911 gunsmith both of us know, he gutted it, gave it a new trigger, hammer, sear, sear spring, etc. and it still was horrible. He had to send it back to RIA to get it to work.
Yes, they have great warrantys, but I beleive warranty should not be used when the pistol is brand new, but after 10,000 rounds and you shot the piss out of it.
For a budget 1911, Springfield GIs are better (once again, my opinion), yes they are both made in the Philippines but the quality is better. I'm not a huge fan of Taurus, but I've yet to see a problem out of their 1911. Ruger (IF you can find one are nice), and the Remingons aren't bad either (triggers suck on the GI model though).
I've heard some people say that their RIA will outshoot a Kimber or a TRP Springfield, but I've also heard people say that their High Points are great and malfunction free.
