I just bought a set of Tru Glo tritium sights for my new-to-me 21SF. I have a large Wheeler bit set which includes a thin socket marked only, “Glock.” I’m not aware of any other nut on Glocks so I think it’s safe to assume this was for the front sight. While it looked to be the correct size for the front sight retaining screw it barely did the job. It seems to be about a millionth of a bee leg too small to fit properly.

I plan on doing a few other sights on my other Glocks and was wondering what the masses here suggest for the best socket for this job. Obviously this Wheeler socket did it, but it was successful more due to my pushing force than it was due to its proper fit.

Thanks.

You are assuming that Tru-glo is using a "common" size.

Best is to ask tru-glo (or whoever is supplying the fastener for the sights you use) for the correct size. Wheeler ass-u-me-s there (or their's) is a common size--- that's why they don't put numbers on the tool.

Well… it was the same size as the factory screw I removed. And my Wheeler tool was just as awkward while removing the original screw as it was while installing the Tru Glo screw.
 
Standard screw head size for Glock front sights is 3/16". The problem, of course, is that there's very little room to work with between the hole and the front of the slide.

I sprung for the actual Glock front sight tool, part number 5686 / SP05686. $25+ from Glock, usually way more from other vendors. The tip has a magnetic insert that is kind of nice, but it's still a bit of a fiddly affair and I'm not sure that it's really worth the price. That said, I won't be getting rid of it either. :)

Does it grip the flats on the screws properly?

I would say yes. The scew head is fairly thin and the tool's recess for the screw head isn't very deep, so you have to make sure everything's lined-up right, but it seems sized right.
 
I got a "Wolf" tool for that screw. It works fine. The usual hang is how the screw head is recessed in the slide and the recess allows only a very thin-walled socket. The original GLOCK screw might work in the new front sight also.
I've switched two screw sights into GLOCK slides. Good thing is neither has ever come loose. True Glows are good sights, man. The True Glo screw fit that Wolf driver perfectly.
 
I found an old driver in the tool box with the right sized head and simply ground down the outside in a taper to get it to fit inside the slide and also down into the recess of the screw hole. Works great but the walls of the driver at the end are pretty thin and I don't want to put too much pressure on the motion of tightening down the screw.

I did the same as you. I bought a set of tools just for the Glock front sight but was not satisfied with the fit so I welded a Craftsman 3/16" 1/4" socket to the end of that tool. Did a little belt sanding. Works great now. I use orange Lok-Tite on my screws but I don't strongarm the screw. Works fine and comes off easily.
 
Like others above I bought a Glock sight tool too years ago. Was not expensive at all. If you are doing other Glock sights it more than pays for itself. Sight changing is simple with the right tool. Night sights last for years.

WIha precision nut driver sku#26547 is an excellent tool for this. Mine has been in use for 10 years, never a fitment problem, list price under $10

Usually the problem you run into with sockets is that the walls of the socket are too thick to fit between the front edge of the screw head and the inside front of the slide. On commercial sockets, they can also have rounded edges that keep them from engaging on the Glock screw, unless you sand the mouth of the socket flat. Wheeler should fit, but they aren't exactly professional gunsmithing gear.

It really doesn't make any difference what brand or type of tool you use. Many sights come with an included tool that is perfectly functional. I have several of those of various varieties that have came with sights and these are what I use.

Wheeler apparently didn’t get that memo. I’ve got a TruGlo tool coming that I hope will fit these screws better.
