I have generally favorable opinions of RIA. They're meat and potatoes 1911s. A bad one will come along every so often, but all the ones I've handled personally impressed me with decent triggers and tolerances that were tight without bordering on too tight. I'd have no qualms owning one. Like any pistol you should fire a substantial amount of rounds before trusting your life to it, especially if you already have pistols that serve that pistol. I have no experience with Norinco 1911s.
