Wanted to post an update.
Jake contacted me through here & PM, I've spoken with him. He was willing to set up a skype session, come in on a weekend, whatever it took to help me to get this functioning. In the long run it was (as I expected) my own error, the Tandemkross bushing is flawless.
My Ruger is operating properly now, mags drop free, the trigger feels a bit more crisp and i'm not worried about parts failure.
Don't hesitate to spend your money with these folks, they'll take care of you any way they can if you need it.
