| Had the pleasure of picking up a new G20 yesterday, and was pleasantly surprised to see that the new standard factory sights are no longer plastic, but alloy. However, for some reason, the sight picture seems messed up. When I make the top of the front sight even with the top of the rear sight (ie fill the rear notch), the bottom 1/5 or so of the front white dot is obscured by the bottom of the rear sight notch. It would appear as though the rear notch is not deep enough. Is this common? Is there a legitimate reason for it? I'm half tempted to take a file to the rear notch and make it deeper... |

Don't touch it yet, wait until after you shoot it at a minimum. Perhaps they want you to line all three dots up instead of the standard tip of the front sight being level with the top we normally use.
A call to Glock may get you a different sight for free. Anytime I ever monkeyed with sights they turned out less than perfect. The cuts must be exact or your eyes will pick up on it. |

I did that on my polymer sight. Quoted: Had the pleasure of picking up a new G20 yesterday, and was pleasantly surprised to see that the new standard factory sights are no longer plastic, but alloy.

Thing is, there are no "three dots". Just the white front and the "u-notch" rear. And the strange(r) thing is, the white outline sits down below the black of the u-notch, if that makes sense. So, if the sight body stopped where the white outline is, everything would be about perfect.

That is normal. All my Glocks look like the front dot is just below the U notch so that bottom of the dot is slightly covered up. Glocks usually shoot point of aim, so you have to cover the target with the dot, rather than have the harget just above the dot.
I replaced all my sights on my Glocks with trijicon night sights since I like the three dots better. |

I have found it VERY common for shooters to think they should line up dots or other sighting aids only to find out the sights are designed to have the "equal height,equal light" method of alignment-that is to say post top level with rear sight and centered in rear sight notch- this often leads to problems as shooters focus is drawn to the dots/outlines etc and then the guns end up not shooting where they are aiming. My personal thing(maybe casue I am an old school bullseye shooter) is to have just PLAIN black sights on all my guns- no distractions - and on some of my carry guns only a front night sight -in low light the front sight is visible and shots at a threat at night are going to be very close where sighty alignment will not be critical. Even with plain back sights, I always carry a flashlight and bet I would have to id a target with light prior to shooting if it wasn't at point blank range- when you use a white light to id target with the gun in 1 hand and light in the other it will cause the night sights to fade out and you end up looking at a essentially plain set of sights again anyway.
gun companies put all sorts of dots and crap on sights because some people seem to like them but do not beleive that the dots are put on with any sort of precision or that they bear any relationship to where the gun will poi poa |

I am also a bullseye shooter and equal height and equal light is the name of the game. Not to hijack the thread, but my favorite night sight is the Ameriglo Operator. They have a .125 front and a .150 notch allowing ample light around the post for day shooting and no white outline around the rear tritium insert. This means the rear sight seams almost black and non distracting. I also like the green (bright) front and yellow (subdued) rear. Just my $.02 worth. |

I just can't figure out why they'd bother to put a white dot on the front sight, then use a rear notch that, when aligned using "equal height, equal light", obscures part of the white dot. It doesn't make sense, at least not to me. Oh, well. Maybe Glock figures that folks will just replace the factory sights with aftermarket options anyway, so why bother to make it right...

Have you got a pic of these new factory sights OP? Are they shaped the same as plastic ones or are they shaped like night sights. Posted Via AR15.Com Mobile After going to look at a older Glock with plastic sights, it appears as though they're shaped exactly the same. I guess I never noticed before because I'd always had 3-dot night sights (Mepros/Trijicons) on my Glocks. I knew stock sights were plastic, but had never paid attention to them beyond that. I'll see if I can post a picture later on. |
