FN Hi Power safety not a perfect fit - problem or not?

Last night, I installed a used Mark-III style safety in an Austrian mil-surplus alloy-frame FN Hi Power. I realize that safeties are not usually drop-in parts, but I wanted to see if it works.

Now when the replacement safety is activated and I pull the trigger, I can hear, or more likely feel, a tiny-little click but the hammer does not move at all. After I do this, and deactivate the safey, and pull the trigger, there is a little bit of "creep" (while I pull the trigger), then the hammer drops normally.

I read on Steven Camp's site that the faint click is a sign that the safety is not perfectly fit to the sear, and upon pulling the trigger with the safety engaged, the sear is allowed to move up just a tiny bit. Again, without any visible movement of the hammer...

I doubt that I can make this safety fit the sear perfectly, since this is probably a sign of a safety that is too small for the sear. I got the safety used, so it was probably fit to another gun a long time ago.

The question is this: the safety seems to be doing it's job and keeping the hammer from falling when the safety is engaged. Is this imperfect fit simply a small annoyance or is a sign of an impending safety failure?
 
A good smith can weld some on the safety, and recut it to fit perfect. I had one done simlarly to you, and that one fit fine without modification. I will be doing another refit of a used ambi to another LW BHP, and we'll see how it goes. I think the minor tolerance can be different from gun to gun, and it is a matter of luck if you DON'T have to have it fit.
