Ruger Mark IV models -- advice?

I think you have hit it perfectly. There is nothing wrong with the Lite version it just serves a different purpose. Back in the day when I was Bullseye shooting we added weights to our Hammerli, High Standard, and Pardini handguns.
This combo works well for me when instructing someone who wants a red dot.
Vortex Venom.

Awesome! I have a Vortex Viper sight. I think I'm going with the Tactical, and probably will add a charging ring and a compensator.
