Re: slide refinshing
Just did that a couple of weeks ago to a Springfield 1911.
Here is how I did it:
Put some 120 or 100 grit sandpaper on a FLAT piece of STIFF metal. You do not want it to flex because if it does, you will have an uneven surface on your slide. Take the flats of the slide and push them across the sandpaper. It will take the finish off in short order.
For the round top, I took a strip of sandpaper and carefully "shoeshined" the top to remove the finish. If you are careful, you will not round the transition area at the junction of the flat sides and round top.
Note: this was a blue steel pistol and had no nickel finish.
Take the Brownells Teflon-Moly finish and follow directions. I think you will be surprised at the results.
