Glock 21 a redheaded stepchild?

[Paul053]

I'm trying to find after market sights for my G21 and started noticing a trend. You'll usually see something like this

Ameriglo glock sights...fits 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, 39

Is the G21 upper cut differently that a sight manufacturer has to make a completely different set?

[G-forceJunkie]

No, but the .45 and 10mm glocks come with a different height rear. The dovetail cut is all the same.

the 21 sight is often the highest they offer and those are built the normal height

heck right now i have the highest one glock makes on my 21 and it still shoots low
