How to Put Night Sights on a Glock 27

Replacing the Front Sight

• 1

  Place the slide, top down, on a surface such as a table or workbench so that the front sight is clear of the surface.

• 2

  Remove the front sight retaining pin by placing your pin punch on it and lightly taping it with your small hammer.

• 3

  Turn your slide over and insert the new front night sight's retaining pin into the top of the slide (where the previous front side just was.)

• 4

  Press down until the sight is level with the slide's surface.

• 5

  Turn the slide over so that the top of the sight is against a surface, preventing it from moving.

• 6

  Place the snug screw into the bottom of the front side base and tighten so it is secure. Use the supplied wrench and take care not to over-tighten.

Replacing the Rear Sight

• 7

  Adjust the sight carrier of your rear sight adjustment tool so that it is positioned directly over the slot that will hold the slide; the sight carrier is the part that moves the rear sight and is moved by the drive screw.

• 8

  Put the end of the slide into the slot so the existing rear sight is being held by the sight carrier.

• 9

  Turn the drive screw so the rear sight is pushed left and continue until the sight clears the slide.

• 10

  Remove the sight from your sight adjustment tool and replace it with your new night rear sight. Turn the drive screw, pushing the new sight into position.

• 11

  Remove the slide from the tool and reassemble your G27 pistol.
