I think I will follow this post as I am on the fence as well about changing the sights on my 40c also. The only thing holding me back is it seems to be very accurate, and I'm afraid to lose that.
I have found so many conflicting/confusing issues that I was going to go to local LGS also, but I'm in no hurry so I will just sit back and watch, or reply if I find something more definitive.
So far, (I haven't measured this yet, don't have a micrometer handy) I have found this info:
Front sight is .160" tall x .140" wide
Rear sight is ?
Front is a white dot dovetail
Rear is "steel low profile carry novak"

Any suggestions? Also, should I be ordering rear sight with .140" width or .156"width?
