Has anyone had any luck with this problem?

My 457 was given to me by my father when I turned 21 and I really love this gun. It was his duty carry and I'd like use it for my ccw.

I just called CT trying to find if they had anything for my 457 and as you all know struck out.

If a CT grip can't be fitted to it are there any other good laser applications for this model? Perhaps a guide rod laser?
