RedHawk 1954 I had one of my older Burris 2.5-7 scopes die last year. Burris replaced it with a NEW 2-7 Plex. You can see through it in low light on 2X. It is much clearer than my older Burris scopes. The Duplex Reticle stands out well also in low light.
I have a couple of the 30mm MatchDot II sights that have a 2 MOA Dot Size option. In low light the 2 MOA Dot set on 1 on the Brightness Dial does not bloom bad. I can see through it in very low light, and also get on target.
My brother has the same 2-8 Weaver scope on a Contender barrel. I was checking it out a while back. Best that I remember the Reticle did not stand out very well in low light.
I have no experience with new Leupold pistol scopes, but I have no doubt they are very clear in low light.
See You At The Range
