I can’t say, but I think the sight is pressed in. I have the Uberti Pocket Police. It does shoot a little high. I solved that, at least for me by moving the target farther back, and changing my point of aim slightly, until I figured out what worked best.
I have an old 1851 Navy, for about forty years now. I shot the dickens out of it, and the front sight fell off. I turned down a brass screw for a new, taller sight. I pressed it into the barrel along with some epoxy. The base of the new sight was scruffed up some, and cleaned. The sight hole in the barrel was also. That was to give the epoxy something to fill and grip. The sight is still in the barrel after many rounds and many years.
:hmm:
