I have two 1911 pistols and both were worked on by Ikey Starks in Denver, Colorado. The first one is a Stainless Government model that he installed Novak Combat sights, competition trigger, flat main spring housing and he fitted a new front barrel bushing.
The second one is a Custom Norinco 1911 with a competition trigger, flat mainspring housing, Nowlin Barrel and barrel bushing. The slide was milled and an adjustable Millet rear sight was installed along with a Millet front sight. Then it was refinished in a reverse two tone finish.
