I have only one custom gun (Wilson Combat Master Grade conversion of a Colt Government Model)----a thing of beauty, and shoots bullets which most certainly must be guided by radar------------this from 1995, and has deteriorated not even a little bit. I have another, a quasi-custom gun, this one also from Colt (only Colt). It's a Special Combat Government Model, circa 1994. While the Wilson gun is so tight it squeaks, I swear the Colt is so loose, it most certainly rattles. The interesting (rather puzzling) thing is the test targets accompanying each gun show virtually identical results----one ragged hole----same range, same number of shots fired.
