Ok...I know there's probably 59 threads...but hey lets do it again. Looking to try a dot on a pistol again. I think I've narrowed it down to a Holosun 407K or a 507k. 407k has a 6moa dot 507k has a 2moa dot with a 35moa circle...and you can alternate between dot, circle, dot with circle. Being new to all this, it seems like maybe the 507 would give me both quick acquisition when I want it with the circle...but turn it off for more precise stuff if wanted. 407 would be kinda between the two...and less to tinker with. This is going on a P365XL for defense type carry...I've got other stuff for plinking and range only use. Think purely defensive type shooting and speed.
