Terrible fit - TruGlo TFX Pro Sight Set for Novak 260/450

I have installed several sets of sights on Sigs, Kimber's, and others. I have a Wheeler Sight Tool and plenty of other tools for this work. I ordered the "Novak cut" for a Ruger SR1911. After three evenings of filing and fitting I was never able to get this front sight in the dovetail. The base of the sight and dovetail don't appear to be of the same shape at all. I don't even want to try the rear sight. I reinstalled the original white dot with no problem and threw the TruGlo's into my "just blew $100.00 junk box". Maybe you'll just need to pay a better gunsmith. I have also heard there is a "trick" to installing Novak sights and you need to call them...who knew?
