I try to keep the pin riding on the bottom of the dovetail, or if it won't, I just push on the sight blade. I know folks are scared of breaking or bending them, but the only issue I ever had was with a XD. That one broke the sight base. If you know how thin they are, you'll immediately see why.
I have been looking at some sort of improved push pins for the front sights. If I can find a source of material, I'd make some like the ones for the rear with a smaller head. So far, I've not been able to locate what I need. I still looking.
