He has the best service (he has called me back on Sunday to answer my questions before!) you can ask for and his trigger kits are the best. Had one on my xd40 and now have it on my xdm 40. The difference is amazing. I use all his springs (other than the firing pin spring), his sear, and a reworked stock trigger bar that I modded myself. I have just (1mm or so) enough pretravel for the trigger safety to engage, no overtravel, and a lighter and much crisper break with almost no creep. I dont think it gets much better on an xd. Only pistol I have ever felt that had a better trigger was a full on custom 1911.
Dont forget to polish every contact point lightly. It makes a big difference.
