im having a hard time finding suitable night sights for my shield .40. im wondering if the full size M&P sights are the same or if they have to be specifically for the shield

You can find sights specific to the Shield here. XD-HS2000.com

thank you, that just answered my question easy enough

Shield rear sights are more narrow than full size and compact M&P pistols.

I am having my new sights installed by this gentleman.

Extremely fast.

He received my slide and sights yesterday and just got an email from him that they are back in the mail. Should have them in one two two days and for only $25.00.

If you buy the sights off of him the sights are installed for free.

I also had him install my TruGlo TFO's which I bought from him......can't beat the free install and quick turn around.
