It does look like a lot like the 4516 with my mods but I did not initially go for that. It certainly does look like one! I appreciate the compliments though.

The grips are Hogue. I too like their looks. I also have a big mitt and they seem to fill my hand like no other brand.
Hogue grips cover most of my pistols whether they are wheel gun woodies or rubber auto grips.
I am a big fan of Hogue grips.
