DIY Glock Sight Pusher

I’ve got a handful of Glock pistols, all of which wear some sort of aftermarket sights. For a couple years now, I have been hammering them in with a framing hammer, and a brass punch. It actually works quite well for getting them into the dovetail, however for fine tuning the sights at the range, it can be a pain.

I was home visiting my parents this last week, and I had the opportunity to do a good bit of shooting with my dad. I brought my Glock 19 with me on the trip, and we noticed that my rear sight wasn’t sitting quite square in the rear dovetail. out came the brass punch and hammer, and we tapped it over a little, but kept going too far. My dad, being the tinkerer that he is couldn’t have this. Shortly after we got back to my parents house, I heard the power tools making noise down in his workshop in the basement. I went downstairs to find him beginning to make a sight pusher so we could fine tune the sights on my Glock 19.

He started with an old aluminum C-clamp. Unfortunately I didn’t get a before shot of it, but I think everybody knows what a c-clamp looks like. Basically, we measured the distance from the bottom of the slide, to the optimum height on the rear sight for pushing. On my Glock 19, I believe this was 7/8″. We then took the threaded part of the c-clamp, and un-threaded it all the way, drilled and tapped a new hole for it, so it would be at the correct height for the Glock’s rear sight.

Drilling and tapping aluminum is pretty straight forward with the correct tools. After drilling the correct sized hole, it was really just one pass with the tap, and it was threaded. We then test fit everything, before cutting the bit of aluminum off of the end of the clamp that the clamp originally threaded through, and drilled and tapped it to be used as a stiffener to keep everything in line when pushing sights.

Anyways, we used an old scrap c-clamp that dad had kicking around his workshop, so I’m not sure where you could find the exact thing, however, I really wanted to put this up just as an idea for you tinkerers out there. I’m sure something similar could be made using a steel clamp, a couple properly sized and threaded nuts, and some creative welding.

Anyways, here’s the pictures. She isn’t real pretty, but she works quite well. (Sorry about the crappy lighting in a couple of the pictures, my light source wasn’t cooperating.)

  1. F.Y.I: That clamp is for attaching a shell to the bed of a pickup truck.

  2. Luke do you sell this pusher by any chance?

  3. Thanks for sharing this Luke, now I just have to find a clamp similar to the one you posted.

  4. Great idea – I just made one and used it to install a new sight. The problem with mine is that the pushing end rotates and digs into the finish of the slide. I tried a plastic insert but the end punched through it. I might try a small piece of brass…

  5. One addition…add a sticky back felt bumper pad to the inside of the clamp to add some slide protection. Good job!

  6. please tell your father thanks a million,now i can go straight to buying my sights instead of a tool that costs more than what it’s used for muchly obliged

  7. I found an inexpensive multi-use pistol sight pusher and have used it quite often. This might be useful to some. http://www.sightpusher.com/New–XL-Tool.html I use pieces of business cards in between the aluminum block and the slide to keep from marring the finish.

    • Good call on the business cards, and thanks for stopping by. I hope all is well out in NV.

    • Not to rain on the parade but this is exactly what the discussion was – a simple and inexpensive means to move a rear site. In my neck of the woods, $92.95 is not inexpensive. I did like your tactical key ring / yawara stick. Nice work on that.
