The OEM recoil buffers arise fairly often on EPay. You can also find them at Numrich. The loss of the buffer would cause the problem.
My PD will feed Golden Saber, Hydra-Shok, and Black Talon with zero problems. Watch the rear sight, as it can shift under recoil. Back in the 1970s, most people settled on a load, and loc-tited the sight.
