I just got a front sight from Night Fision for my P10c. Everything went smooth until installing the set screw. It goes in until there is about 3/4 to maybe 1/2 of a thread is sticking out and is not flush with the new sight. Is that normal or has anyone else experienced this? It is not that viable when looking down the slide, you don't see it coming up into the new Night Fision dot when aiming.
