UBERTI 1873 Cattleman Short Stroke SA .357 Mag / .38 Special 4.75" 6 Round Revolver | Case Hardened. The Uberti Short Stroke SASS Pro single-action revolvers are designed with one purpose in mind: saving time in competition. This model achieves this through a short stroke hammer with 20% less travel than on a regular SAA revolver. The hammer is extra wide and low-profile, offering positive cocking and an uninterrupted view of the sight picture. Lastly, the custom-grade mainspring encased in the checkered grip ensures smooth operation and a crisp trigger pull.
