Still gun shopping. I found a Taurus 992 4" barrel that weighs 38 ounces. They also make an "Ultralite" version of the same gun. Weight is also 38 ounces. What am I missing? I thought the Ultralite might be lighter. Model numbers are 992B4 for steel & 992SS4 for the Ultralite. On the Taurus website weights aren't given until I clicked the "Ready to Buy" box.
