    Ok...looking for the cheap way to do this. I don't want to buy the sight tool for my G27 (has factory adjustable sight). Has anyone removed sight without the tool. I'm not really fond on using my punch set to beat on the new sight. Wondering if a bar clamp would work. Any ideas on ways to do this? Also my front sight does not have a screw it looks like a tab, ideas to remove this?

    The front site is the older model plastic one that has a finger that pokes down through the hole in the slide and then a shin gets pushed up into it from beneath to hold it place.

    First question is do you intend to reuse the sights? If not just grab the front with a set of taped wrapped pliers and pull it off. On the rear I've tended to find that any site pusher other then the Glock made one tends to distort the factory site and make it want to come loose real easy and move around. You can drift it out or pull it off easily, but there is a little metal tab that holds it inplace that you will need to drift out as well that you will need to drift out as well.

    For the sights you'll need a hex but t if the set doesn't come with the tool or you can get the LoneWolf Glock tool which will do most aftermarket sites and Glock metal sites and the new plastic ones. On the rear if you can't get a site pusher you are pretty much stuck with the punch. I think using a clamp you would run the risk of distorting the rails and slide unless you had a spacer to put in there.

    I just did mine and the rear you need the sight pusher tool. I know is not a cheap investment but I figured at $25 bucks each for instalation by a gumsmith I might as well buy it and do it myself. I have 2 glock and thinking about buying 2 more in the future. That will be $100 bucks for installs. The tool was $125 with a front sight hex tool and shipping included.

    The tool makes it really easy to swap the rear. i will not use a punch as there is a chance the vials crack.

    The front sight you describe is stake-on. It can't be reused, all you have to do is pull it off with a pair of pliers, with care that you don't slip and scratch the slide with the pliers.

    I did mine with a LWD multi-tool that's made of brass and has a front sight hex nut wrench, and a vise with hammer and delrin punch. The sights I installed were Glock factory steel sights, not night sights. I wouldn't tap a rear sight with tritium vials, it may rupture the vials. The LWD tool had some flashing in the walls of the wrench, all I had to do was run a razor through the walls of the wrench to remove the flashing. To install the new front sight, I degreased the front sight and screw with rubbing alcohol and thoroughly air-dried both. I then put the front sight in the slide, put the screw in the wrench with the threads straight up toward the ceiling, and used a q-tip to apply a small amount of blue loctite to the threads of the screw. Then I looked through the muzzle hole in the slide to position the screw correctly in the front sight, and I tightened the screw down most of the way until the sight only had a little play in it. I moved the sight to be as best aligned as possible, then held it down firmly against the slide with my thumb while I tightened the screw down with only the amount of strength from my thumb and forefinger turning the front sight tool. I then checked that the sight was aligned correctly by eye. I let the loctite set for 24 hours before applying any oil anywhere near the sight, and I let it set for 48 hours before shooting with it.

    The vise part is tricky. If you do it wrong, you could destroy the slide. You have to pad the gripping surfaces of the slide obviously. Also you don't want to apply pressure to the slide rails, the ejection port, or any portion forward of the ejection port. You can use little strips of wood covered in masking tape, I used layered cereal-box cardboard taped to the vice. I used a DPMS AR-15 Delrin punch(it's plastic) and a hammer to tap the old rear sight out, I tapped the sight out toward the right side of the slide. Then I put a drop of oil on the bottom of the new sight and another drop in the slide dovetail, and tapped the new sight in from the right side of the slide. The tricky part is getting the sight centered just right so there's an even amount of extra space on either side of it, that probably took me 20 minutes.

    Here are two pictures showing where to grip the slide in the vice, you'll likely need to use small pieces of wood so that the slide will sit high enough in the vice without putting pressure on the slide rails:

    the hammer/punch is alright to install but the tool is so much easier when zeroing in, I found it almost impossible to use the punch to move the sight 1/32" so I bought the tool and also have 4 glocks. I also found it useful for other weapons as well. The tool is 100$ but I have drank that up in a nite out.
