Loose front sight on a Mil Spec

[maui-onion]

I was wondering if this can be remedied myself. It's not super loose but I would like to get it fixed. I dont' want to have to send my gun off to SA for a problem this minor and I don't really want to have to pay anyone to do this. I would like to learn how myself anyhow. Is there any DIY solutions for loose sights?

Any input will be greatly appreciated.

In theory its pretty simple, but smiths have a special tool they use to peen the sight tight and maintain proper alignment. An issue might be, whether the current sight can be restaked, or whether it should be removed and replaced.
My choice would be to send the slide back to SA for proper repair.
