Speaking of triggers I didn't know what a "buttery smooth" trigger was until I picked up my used Smith 686. A buttery smooth trigger is something to experience and you won't get one on a Ruger without paying for a trigger job.
I still like my GP100 for what it is. A very overbuilt, no frills tank of a handgun.
Back to the original question, if I were in the OP's shoes I wouldn't hesitate to buy the RIA 1911. Yes it's built in the Philippines but it is rock solid and it's a 1911. Buy it, prove it by putting a hundred rounds through it and you've got a whale of a carry gun + home defense gun + great range gun.
Being a 1911 there are many many add ons, custom items and other fun things to do with it. Another plus is that you will be thoroughly familiar with the 1911 platform when you do finally get the Springfield Armory GI.
