You can ask the SIG SAUER Pro Shop 603-610-3456 (I got some of my sights there). Some vendors specify the sight height. But don't leave it to chance, it's really frustrating when the wrong sight arrives, I've been there.
You can use a SIG sight tool to be safe, or do a careful job with a punch and a hammer. SIGs sights are not Glocks, they can be tough little mommas. I soaked them in Break Free for a couple of hours before getting to work.
