I am looking for replacement sights with a wider notch and tritium to replace the factory Novaks on my 1911PD.

I have heard S&W has a non-standard dovetail so I am hoping someone here can point me to some options.

I have a set of Warrens on another handgun and like their set-up but I am willing to look at others that will fit on a S&W 1911.

Thanks
