I have a HP Practical done by Jim Garthwaite. When he finished it he mentioned the extractor may need adjustment and it did. After that it runs like a champ and it is the most accurate 9mm I own and I have a bunch. He also put the Gold bead front sight , his trigger and hammer,
Jim has done lots of work on my 1911's also.
I have the same 9mm FP load I shoot for my M&P's , Glocks, Trojan with 9 lb spring. I had FTF with the conversion gun on this load. I'm presently working a load for it know. Going Roundball 124's with a few more grains and longer OAL then the FP.Jim told me when he did the conversion that it may prefer a little hotter load. It hasn't had any problems with factory 124 loads.
