See pics, it fit right on on my 24's. Maybe yours was drilled wrong from the factory?The hole in the rail for the anti stab isn't centered on the 24 the same way as it is on the 23s - the tip hole does not line up with the rail hole and if you Dremel it out, you get a oval shaped hole with only a millimeter of plastic supporting it. It's sketchy. Have you actually done this install?
