I recently purchased a Glock 17; and I took it to the range for the first time today. I've had a decent amount of experience with rifle sights, and shoot "pumpkin on a post" style (like sight picture 1). However, I shot a magazine like this and I was hitting about 6"-8" low at 25yds. So I then used a sight picture like 0 (with the dot obscuring the target), and I seemed to be dead on. This was with the standard plastic non-adjustable factory sights, with the factory zero.
So which sight picture is considered correct for a Glock? I'm also looking into buying a pair of Trijicon night sights, and I was wondering which way (0 or 1) is considered proper with those. I'd prefer sights that align like 1, because I've shot long enough that I instinctively line up the sights this way.

Zero (0) is correct for a stock Glock. But I forget what range the sights are dead on at. I think they are sighted in for 10-15 yards, but I can't remember. It probably wasn't perfectly dead on (I was shooting offhand), but I was able to hit the 4.5" clays I was aiming at, without compensating. |

But I forget what range the sights are dead on at. I think they are sighted in for 10-15 yards, but I can't remember. I posted the information below in another thread, taken from the 10-8 web site. It has me thinking of changing the front site only on one of mine. I need more range time with it before I decide. SOME IMPORTANT NOTES ABOUT GLOCK SIGHTS:
Factory Glocks tend to shoot anywhere from 2-4" high at 25 yards, usually necessitating the use of a 6 o'clock hold when shooting bullseye and other small targets. Keep in mind that if you lined up 20 Glocks, all of the same model and caliber, not every single one would shoot to the same point of impact with a given set of sights. Glock makes a number of different height rear sights to accommodate the inherent variations in points of impact. With this in mind, an aftermarket front/rear set with a standardized height for all models - such as the one we've been selling for a few years now - can only provide an approximate elevation setting for any particular gun. The .215" height is the most commonly used of our front sight heights, and typically provides a point of impact from 0 to approximately 2" high at 25 yards. Results will vary with individual pistols. The .235" height front sight lowers point of impact approximately 2-3" at 25 yds from the .215" tall front sight, and the .250" height lowers the point of impact approximately 3.5-5" at 25 yds, depending on your model's sight radius. One inch of elevation change at 25 yards equates to approximately .007" of front sight height. We do not recommend sighting in your pistol at any distance closer than 25 yards, as the amount of possible error generated by sighting in at shorter distances will create issues when you shoot at longer ranges. So how are you supposed to know what to put on the front of your gun to match the rear sight you got from us? Currently the simplest answer is to leave your existing front sight in place, shoot it at 25 yards with your new 10-8 rear in place and print a group for elevation. Measure your existing front sight, and using the .007" of front sight = 1" at 25 yards equation (I know, no one said there'd be math...), figure out how much taller or shorter you need to go. Everyone tends to like or accept different elevations, which further compounds the difficulty in preselecting a front sight. I like my guns to shoot about .5" to 1" high at 25 yards so that I can see the point of impact over the tip of my front sight blade. You can also use our Glock Sight In Tool, a plastic one-use sight blade, to sight your pistol in by filing the front sight height to fit. Once sighted in, remove the Sight In Tool, measure it, then order the correct front sight. |

i thought sight picture for factory glock sights were like 1?? You are correct for almost any handgun. The only time you should NEED to compensate is for larger range differences. Like between 25 and 50 yards. This is also as you probably already know is going to differ with barrel length and especially with the ammo used. |
