Basic semi-custom production of 1911 and 2011 models. Fit all the small parts to each gun mostly. Safeties, triggers ,sears and diconnectors, plungers, mainsprings, slide stops, etc... it all has to be massaged and fit and look good.
Assembly, polishing slides, sights, bluing,...pretty much everything except barrel fit and slide to frame fit.
I could pull one apart, clean up all the small parts, reassemble and do the final checks before paint or bluing in 7 min. It was fun but the company sucked.
