Looking to replace the factory sights on my PPQ with a set of Trijicon HD night sights. Does anyone know what size flat head screwdriver I need for the rear sight? Thanks.
Thanks, this helps alot.Put on some safety glasses. Use thumbnail to depress the plunger. While holding the plunger down, use other hand/finger to push sight about 1/8" to the left. Now, carefully release pressure on the plunger, letting it come all the way up. Be careful, the plunger has a spring under it and if your thumbnail slips off, the plunger can make like a saturn rocket....either bouncing off your safety glasses or punching through the roof enroute to the moon.
Once you've got the site pushed over a little and your thumb off the plunger, you can then finish pushing the sight out to the left.
The windage screw has a concave slot for the screw driver....I use a file and do a little filing on the end of a small screw driver to make it match the slot in the screw head.
The windage screw is left hand thread. Meaning to remove the screw, you'll need to turn it clockwise.
Put the windage screw in the HD sight and install the sight in the reverse order of the removal process.
This should help:
