Wearing the Duke Arms name, the Mustang .357 is based on the Colt Python, a .357 Magnum revolver known for its clean trigger and long barrel. It fires slow but hits hard, and the sights make it a fine choice for careful, deliberate shooting. A classic revolver feel dressed up for the new setting.
A gun store in the Ammu-Nation style is the most likely place to buy the Mustang .357. Since Rockstar has not shown how GTA 6 gun shops operate, the counter, cost, and any unlock steps are not confirmed.
