Dan..thanks for the info. I didn't use a vise, so that might do the trick. I know that the sight has to be removed in order to remove the Striker Safety Plunger...that's another reason why I wanted to remove the sight. I think putting that spring under the sight might have been a bad idea on Smith's part. If I get the sight removed from the slide I will trim it just a bit so that I don't have to hammer it out every time.
