my own experience with the np29 is that they are a bit rough out of the box. Doing a few things has actually made a huge difference. A little de-burring here and there, doing some polishing on the hammer, sear, ramp, change out the leaf spring, sand down the rails where they need it, change a few mim parts like the safety, installed a better adjustable trigger, a better barrel bushing and a few hundred rounds down the pipe and it operates as well as some that cost several times as much.
As a cheaper platform to practice your repair/build skills and learn they are great....it just takes patience and tapping into the HUGE knowledge base from other owners of 1911's.
Is the norc a top tier 1911? NO....but for someone who likes to tinker or (i have read) they can be a great start for a quality build.
