Just got a new 1 of 1,000 Lipsey Ruger Falt Top Combo revolvers. These are SS 4 5/8" Bbls white grips. The warning is faint under the barrel. These are .45 Colt and .45 ACP calibers. They are on the old .357 frame and the old XR3 grip frame. They have the Micro rear sight. The balance and 3 lb. trigger makes them an off hand shooter. These guns have the new cylinder bore process so every throat is the same. A nice SA .45.
