My mod turned out OK...Had the same gun with a stainless barrel, nice shooter.
Big issue of course is figuring out how to disassemble, not a picnic but it's not as bad as people make it out to be. Buy a rubber mallet.
I didn't like the grip on mine from the polymer grips so filed them down and threaded them for some Hogue 1911 grips. Bad idea, it turned out like crap and wound up buying another lower for it and giving it to my brother in law.
Nice.My mod turned out OK...
