I think I just read that someone is offering these with an aftermarket upgrade, that included all of the normal "1911" stuff you would look for, for about a $300 bump in price. I can't remember who it was, but I'm sure someone on here will know.
got over 1500 rounds through mine put a Wilson Combat spring kit in it all Springs, Main,sear,magazine, Firing Pin, Recall Spring shot 200 rounds this week. Spring really smoothed the shooting of my pistol. Never a malfunction even with Tula.
