I just picked up one of the Lipsey’s stainless Blackhawk Flattop convertibles in 45LC/45ACP with the 4 5/8” barrel. It weighs right at 40 oz, and being a mid-framed model (as all the New Model Vaqueros and Blackhawk Flattops are now), you cannot use the Tier 3 Ruger Only loads like you can with the large framed models. That’s fine with me, it will still handle Tier 2 ammo which works fine for deer hunting at reasonable ranges, and as I have a truckload of 45 ACP, it will primarily shoot that through the second cylinder. Haven’t had it out to the range yet, buy it feels great in the hand, and is a great looking revolver.
