Just ordered night sights for my gen 5 and was shocked to see they called for a different part number than a gen 4...whats the deal with that?
Everything looks the same...

Great point, and I'd like to point out the ATF's point system is unconstitutional, and not just regarding Second Amendment concerns. Just as important, and in some ways more so, the ATF is an agency under the executive branch and this violates the separation of powers the constitution requires. And since it was passed by legislation rather than constitutional amendment, it is utterly unconstitutional and thus illegal.None of the responses so far explain what appears to be the *real* question:
"Why is a Gen5 OEM night sight set different from a pre-Gen5 OEM night sight set?"
Gen5 pistols come from the factory with a different style OEM polymer sight or OEM night sight (ignore Ameriglo) than do earlier generations. These Gen5 sights are designated GMS for "Glock Marksman Sights". These are considered "target" sights, while the earlier generation sights are not. These GMS sights meets the BATFE import point criterion for "drift adjustable target sights" and gains five more BATFE import points for a Gen5 pistol.
Gen5 G19 and G26 pistols need these points because instead of the "target" grooved-face trigger of earlier generations, they come with "non-target" smooth-face triggers. That causes a loss of two import points, but that is no problem because of the five points gained by the GMS sights. All Gen5 pistols have smooth-face triggers and yet all remain importable!
It's all part of a game that's played to get GCA68/BATFE import permits for small pistols. "Target" features get more points. Seemingly insignificant changes can almost magically change a non-target feature into a point-winning target feature.
Thus this to the OP's observation, using a G26 as example:
-> An OEM night sight-equipped Gen4 G26 uses 4.1mm front night sight part NF17G24 and 6.5mm rear night sight part NR17G24. It actually requires no special sights for importation because the sights are NOT used for import point assessment.
-> An OEM night sight-equipped Gen5 G26 must have 4.1mm front GMS night sight part 39750 and 6.5mm rear GMS night sight part 39745 for importation because the sights are "target" sights for import point assessment.
Ameriglo sights, if applied outside of the USA, would qualify as target sights for import point assessment.
The Gen5 G17 and G34 and G19X are large enough to require neither special sights nor triggers for importation.
The sights sold by Glock form now a large array:
-> Non-GMS polymer, steel, luminous, and night sights - Fixed front with various rear sight heights.
-> GMS polymer and night sights - Fixed front with various rear sight heights.
-> Ameriglo night sights - Fixed rear with various front sight heights.
These options may be seen in the Certified Armorer's Parts Order Form found at:
I too liked the factory sights until my eyes started to betray me in my mid 40s. I chose the Ameriglo I-dots and put them on a gen 3 26 and gen 4 20. Love them. Shoot a tight 6'oclock hold just like every other pistol I owned before the tragic boating mishap. My disappointment is that Ameriglo didn't mention the regulation differences with their gen 5 sights. I'm 2' low at 10 yards. Looks like I'll be dropping another $50 for a .180 front.I have the 6.1 poly. rear sight and no idea what my front sight is on both of my G45's.I like the OEM poly. sights on Glocks,I am probably the only one on this board that does.
but just curious if you run the .180 in the front how does this affect a longer shot say around 25 yards ? I am looking into getting the ameri glo spartan tactical sights to put on my gen 5 19 and I would like to have that 6’0 clock hold. But just wanted to hear your thoughts/experiences with further shots. Thank you for your time.This is the rule with the Ameriglo sights.
The 5th Gen guns come with a .200 front sight typically. This gives POA/POI right behind the dot on the front sight. For most folks they hit low.
Most of the combat type sights listed for other models have a .180 height front sight.
FWIW I run .180 fronts on all my 5th Gen pistols. Their POA/POI are right at the top of the front sight. Closer to a 6 o clock hold.
The same is true with the 19X as well, although they come with the factory glock sights. I use the Ameriglo Agent sights on them as well with a .180 front sight.

Thank you sir I appreciate your help. I am looking into setting up all of my glock pistols this way. I will report my findings once I get lucky enough to find the parts needed.I can't speak to the impact of running a shorter front post, only thing I would say is that I believe the spartan tactical set may come with a .180 front to start with due to the lower profile rear sight. You may have to drop down to a .165 front to accomplish the same thing on the spartan tactical set, but worth confirming with Ameriglo.
