I have never been a big fan of the the front sight on the glock because it is so wide. Today I removed the stake from the front sight, removed it from the slide and thinned the profile. It isn't that much thinner, but it does let a little more light around it and it gives a little bit better view of the target. Most likely I will replace these with aftermarket sights tha I like better, but this is a easy, quick and cheap fix for now. Has anyone else had any success with this? Attached are some pictures of the newer thinned out profile of the sight on my 21C vs,. the thicker sight on my 30.
