I dont understand the need for a “chest rig”.
A ruger super redhawk can be comfortably worn on the hip, and there arent many revolvers out there that weight much more than that. Maybe the x frames, but not by much. Tighten up your belt a notch! Just my opinion
They’re more comfortable than having 4-lbs hanging from your waste. There are scant few belt holsters made for revolvers sporting optics and chest rigs are the best option especially if you are putting in the miles. Plus you can sit comfortably while wearing a chest rig.
