Both Springfield and Dan Wesson have optic ready options if that's what your after and both make better 1911's. Look for a Springfield PX9110ML18-RMR. They're out there and usually about $1400 with an RMR Type 2 mounted.
The S&W E-Series aren't terrible if you can get one cheap, but milling it for optic is going to void the excellent factory warranty, which would be half the reason to buy that particular pistol.
