Night sights for gen 4's

[Mathwiz]

As I check the web sites for night sights, I find no reference to compatibility with the new gen 4 guns. Can someone confirm that if a web site states G27 for instance that it will work for the gen 4's as well as the gen 3's.

BTW, my G27 gen 4 has a nut on the inside of the slide under the front sight. I believe the gen 3 guns are press fitted. Is this correct?

Thanks in advanced for any insight on this.

They should fit Gen 3 and Gen 4, there was no change to the dovetail on the slide...later Gen 3's and Gen4's have screw front sight...

Older front polymer sights were "pinned" in place. Older factory night sights were crimped into place. Glock switched to screws around March 2009.

Any sight designed for a Gen3 will fit a Gen4.
