Both those pistols in the photo have different triggers than my UG P07. They are much more curved. And, the one on top has the decocking lever on the wrong side of the frame - the right side.
The one on the bottom appears to have the NSN number on the frame. Mine does not, nor have I seen on made like that, not the Urban Gray Omega.
The one on top appears to have the front strap checkered, not the vertical grooves mine has. The bottom pistol doesn't look to have any grooves or checkering on the front strap/frame.
Also, both of those pistols have the older ring style hammer on them instead of the newer flat topped looking hammer the other Urban Grey P01's I've seen use.
A couple odd looking pistols there.
