Early 90s aftermarket Glock front sight, held on with this (below). Can't find anything that size or drive to even try to turn the screw. Any ideas what that drive is called? Several people have suggested it's staked in there, but I'm not sure how I would have done that in 1993 since I had no tools but what came with the sights.

I don't see SQ00 bits anywhere, but check this out... this kid has those two to the left of the SQ0 bit. Kinda looks like that.

Try this. Look at the picture blown up in the bottom section left side two rows down from the hinge.
Looks like a flat screw driver with the middle ground out leaving two pins. I blew up your picture and it looks like it has 4 holes in it but hard to tell.

It's got 4 holes, and those 'prong' bits are WAY too big, I've tried basically everything you're showing in that kit (I have several kits like that). nothing matches.

I'm likely to just have to drill it out or cut the sight apart on the other side of the slide.
 
A two prong bit will fit diagonally in one with four holes if it is the right size. Just how small is this thing? Could you file one down to fit?

It's between a 1.2 and 1.3mm bit of another type, so small.

I know a guy with a drill press.... We may just be drilling that out if I get that desperate.
 
Any chance it’s a watch screw? Could the driver be something like one of these?

Who is the watch repair guy on the forum? Maybe he can answer.
 
Try a flat bladed jewellers screwdriver. I usually use a flat blade screwdriver on case backs with Philips screws. A nice sharp blade works in most cases.
 
Hard to tell from the pic, but it looks like a phillips head that's stripped out.
I was thinking this as well.

And I've done this with the above scenario.

When I was a kid, I had big steel balls. :cool:

And I remember taking those apart and nailing the halves to 2x4's and making scooters or the original skate boards. Kids today have no idea. We used to have to make our own toys. :D

I did that,


only once.
 
My screwdriver set set has blades that are .50,.60,.80,1.00,1.20,1.40, up to 3.00mm. If none of blades fit quite right you can alter the blade fit using a sharpening stone, that’s how I keep mine sharp.
