I am going to put an optic on my P-01 Omega which I use as my carry gun. Pretty sure I am going w/ a Holosun EPS. For referance the EPS carry is about the same size as a 507K and these are the optics recommended for micro/single stack pistols. The regular EPS is not that much bigger and I would like a bigger window, but again, this is my carry gun.
