The 2011 is the gun, I actually am not sure what the optic is on that either! Welcome to the wonderful (and expensive) world of firearms!

Edit: the sight is a Trijicon RMR Type 2 Red Dot Sight

Yup as the other poster mentioned, the 2011 is the gun. I’m particular, this is a Staccato C2 DPO with a Trijicon RMR red dot on it.

The 2011 is based on the 1911 platform, but double stack with a detachable grip.
