Well, if you think those are hard to find??.. Try to find a Ruger Super GP in 9mm... As far as the S&W 929's, I had 2 at one time. You had to do all the little things to run with the boys. Your not going to get a "tuned" firearm from the Factory from either "Custom Shop". I wasted a LOT of time trying to get cheepo, sloppy moon clips to work, buy TK's and be done with it!. (Even TK has several that vary in tightness). Mike... PS, Pick one brand of brass that works with your moon clips, TK will tell ya.
