I bought two of them. I was able to fit a 2" Numrich barrel to one, but they have since run out of those barrels. I put a 4" on the other, and as was noted by a previous poster, changed out the center pin and ejector rod. Both made up into sound, mechanically good revolvers. They are not cosmetically anything to write home about. There is heavy stamping on the bottom of the frame in front of the guard from the agency that used them in (I think) South America. Use a proper frame wrench (and not a hammer handle through the frame window) to tighten up the barrel.
