Is your Colt large pin? The later models where they went back to regular pins and pivot hole have been better from what I’ve seen. Though I do remember seeing a few pics of new 6920’s that were rough.
The pin hole trouble I had was they were drilled in the wrong spot or at an angle causing sear fitment issues. My other one from the same batch is perfect.
It is a pre ban gun, so you would know better than I. I have not messed with the pins or measured them. Its pretty much bone stock except for the grip and adjustable aperture.
