Sorry I was in a rush and didn't answer your questions.
Funny thing— I bought a near identical slide to start,
and the the hammer area needs to be cutout, the rear
sight area has to be enlarged cause the stock sight
drops down inset style. I gave up on that slide after
alot of work. It's not a drop in job, expect a fair bit
of cutting and modding to use that slide.
Those slide pics always piss me off cause they fail to
show the rear where the hammer strikes. Yours needs
to be completely cut away, that one has a full plate
as is expected for SCW's. I know, I looked via the slide
name just like you are, but there is no identical slide
replacement for your stock one.
Edit: see my past sale:
