What is your opinions on the Urbino stock for the M1 or M3?

I purchased an M3 years ago in the hope that someone would eventually address the LOP issues with that gun.  I like the Urbino stock on other models, but I have read that it wasn't quite designed for the M3.

What I'm wondering is how bad the mismatch is. Do you like the Uribino on M1?  I have searched for a picture and am having trouble finding one on a benelli other than the M2 or M4.  

Thanks!
