Basically, I did almost all the list that GunBuBit posted. I had Printz firearms in Essington PA do the porting and silver cerakote. I replaced 90% of MIM parts and I had KI Precision in Vineland install Atlas trig and tune it up. They also did the "bob marvel cut" which makes a HUGE difference. 2-2.5lb trigger and racks like butter. KI said they were going to start selling it as a package, with the Prodigy, for 25ish, which seems a bit steep to me. I got a deal on BNIB for 995, plus like 700 in it? So I'm not complaining. He had 2 prodigy, 2 stacatto, an Atla and a masterpiece arms in the case that I got to man-handle. Only the Atlas and MPA made me drool. The two stacatto and my prodigy were about the same. Not saying they are the same, just felt the same. Then again , I'm at the price of a Bul Armory sas ii, so yeah, I'm grinning like a prarie dog in heat
