Frequently asked questions

Can I change the sights on my Glock 21 at home?

Yes, with a sight pusher or a punch. Drift the old sight out of the dovetail and push the new one in. For the front sight you need a Glock front sight screwdriver. If you do not have the tool, a gunsmith can do it for you.

I use a red dot on my Glock 21. Which sights should I take?

The tall co-witness sights. You see them through the window of the optic, so you have a backup if the red dot fails.
