I run one of Virgil Tripp's new 1911's as my main competition piece. A 9mm and a 40 top end.
BUT, for my backup, I picked up a RI in 9mm. I replaced barrel bushing, added a tungsten GR, SV AL non pivot Grip safety, DP ICE magwell, Ed Brown Extended mag rls, and VZ grips. Gave it a trigger job to 2.5lbs and added grip tape to front strap. All in a little over $1k but it runs perfectly. Would not hesitate to run as a main gun (actually its for sale as well as moving to Open next year)...
