I need to drift my rear sight, but I think it's glued in place. I used heat, a large punch and a good sized ballpeen hammer after my sight tool wouldn't budge it. I tried soaking it in boiling water, in case they used Rocksett, no luck. I sprayed Kroil inside the set screw opening and let it soak overnight. Nothing.

Do I need a bigger hammer!

Buy a sight adjustment tool.

I have a VISM sight adjustment tool. It won't budge it.

I can’t imagine where they might hide a setscrew on a 1911 rear sight…  Maybe this is a job for Kroil?

I’d call SDS and ask them if their is anything unique to this pistol to why the sight won’t budge.

Some Ruger 10/22s had their front sights soldered FWIW.

The rear sight on my Tank Commander was a bitch, too.

I got my sight pusher on it, torqued it down as hard as I dared the direction I wanted it to move and smacked the end of the sight pusher bolt with a brass mallet.
 Took three times but the sight finally moved with no damage to the gun or the pusher.

I put mine in a vice and pulled out a framing hammer and a heavy duty steel punch.

It came out after 10 good taps, but I was sweating for a minute.
