Reddit reviews Handgun Sight Tool Universal for Front or Rear Dovetail Sights , Glock, 1911 or Other Handguns with Parallel Sided Slides.

I got this one. No complaints, does what it should and it hasn't broken yet. This one looks alright too. Doesn't make sense to me to spend much more as I'm not a gunsmith.

I got this, this, this, and this. If you're doing it only once then it may be worth it, but if you're gonna do it for multiple sights then you might wanna get the tools.

Get the sight pusher if you think you might own more than one Glock or if you might want to experiment with a couple different sight setups.

I've got one pretty much like this and it's more than paid for itself.

Edit - There's also this one for the front sight. I have this, but it was really too deep for me, so I filled most of the socket with Gorilla Glue and it's perfect now.

I got this one. works well for flat sided slides. https://www.amazon.com/dp/B016X5STKS/ref=cm_sw_r_cp_apap_CtHcyOJ24N8dW

i found the 35 dollar amazon ones work pretty well. i went somewhere to get my sight pushed back in and it was gonna cost 35. this did the trick in 10 minutes.

Hey! I have an M&P Pro, I installed an Apex comp trigger kit in it - to do so required removing the rear sight, you're absolutely right you have to remove the set screw on top of the sight and then drift it out (which I found to be nearly impossible by hand, either my dove tail was crazy tight or something was holding it in - I used a lot of kroil and purchased/used this sight pusher from amazon to get the job done. You might have better luck moving it than I did, but heres a couple of videos on YouTube which is a great resource, good luck!

Most of the people who complain about these universal tools couldn't figure out simple things like having to flip the slide around to use the beveled side of the pusher when putting the sight back on.
