I ordered some Glock night sites for my G22 which should be here tomorrow. I didn't have a front sight tool yet and didn't want to wait for one to get here so I made one. I had a $13 Kobalt hand driver set that I took the 3/16" driver bit from. I ground down the end that the bolt head fits in to then ground down the walls so it would fit on to the bolt on the front sight. It works very well and didn't cost me a lot of money. Now I have a Rear sight pusher and a Front sight Removal tool. Thinking outside the box can save you a little bit of money and get things done quicker.
