Hello, I have a question that I want to address. It seems very strange that my GP100 that I recently purchased doesn’t have a spring plunger retained front sight hole when I tried to detach to switch over to my newly bought HiViz sight. I can’t understand because I’ve been looking at the manual and online videos which they all state that all GP100s should have the hole right above the muzzle to pin then remove the sight. Do you have an answer to this please? Thank you!
