Excellent! Thanks Cane! I'm having a lot of FTF's on my RIA CS model (first 1911). The slide was pretty rough cycling. The lapping compound really helped to smooth it up a LOT. While I was at it, I applied the same treatement to the barrel bushing so I no longer need to "tap out" the bushing. Cleaned and oiled and it's much smoother now (also helps reduce FTF's when you don't install the spring backwards on the guide rod LOL). Still getting some FTF's, but will address that in another thread.
The lapping compound has already found another application - loosening the pivots in my leatherman just a tad ;-)
