Sight Modification
When you selected an off-duty gun in the SS (you only had about two choices), it had to go the WDC and be signed off by one of our armorers. And you couldn't work on your OD gun or your 2.5" issue Model 19. Anyway, I sent a Model 60 up and it came back with the front sight shortened. I still have the revolver. I called them up and asked WTH? They said they did that so it matched up with our issue ammunition, Federal 110 gr., controlled expansion bullet, +P+. I never had any trouble hitting the target before or after the modification. I agree with other posters. Unless you just can't stand the sight of it (no pun intended), try some other ammo in it. I wouldn't think you were going to be firing it at more than 15 yards if a self-defense gun. Any more distance than that and I personally would be running, looking for cover.
I just remembered it is a half-moon sight. That would be hard to take. Good luck.
