I was bored and browsing a tiny LGS here, listening to all the racist banter about Hillary when I came across this at a great price.
Taurus PT1911 AR

So where do I being polishing a turd. I've already started with some simple work, like a rough polish of some bits like the outside of the chamber to try to get a mirror finish as opposed to the matte in the above picture, as well as the feed ramps which immediately made ammo chamber a LOT better.
Now that I've done some free work, where should I start with parts/what are the must haves? What can I do to smooth out the main spring? I've begun looking at springs, guide rods, buffers, etc. Which of these parts make the biggest difference? Also I've read the Taurus mags are the weakpoint of these guns. I had zero failures with 100rds, but may replace them down the road.
