Just talked to Mike.
The sights are identical to factory Glock in width in front and the notch. Mike has messed around with various beads and while they looked good in the low ready, on target he found them particularly hard to see. He also shoots a lot in "suck lighting" indoor ranges that have the same crappy lighting as cops will find inside buildings. The brass is now set up to give maximum feedback (he says the bead is amazingly brightwhen you are actually looking through them). You can see light bars when looking through them and he will have the company doing them post pictures of what they look like looking through them. What Mike emphasized is practical for what he likes and how he carries. Mike is a actually carries all the time guy, and it's usually front appendix with a full size gun. He got tired of getting tore up on skin and clothing, so the sights are contoured to not shred skin and clothing, but also angled to allow him to press check or rack the gun easily with them. They are Nitrided to 70 RC and super hard so they can get dropped and hit and not be easily damaged. Mike is very hard on his gear. His stuff is always jacked up looking, so I understand why this was important. He says he can hit easily to a hundred yards with them, but the key for him is working indoor problems at speed. Mike is sending me a set. I will check to see if I still have any Glock sides in my parts box. What I may do is set up a slide and send it to folks here to try. Or......maybe break down and get a newer gun to try them on.
