EMP 3", ran great for ~~200 rounds, changed ammo manufacturer, still FMJ, brass, 1st round fires and ejects, 2nd round jambs in barrel, won't fully fall in, keeps the slide from closing fully, round is unfired, slide then sticks and won't move, not a safe scenario, purely an ammo issue, or need trip back to SA? It's done this twice now, not sure I want to try it again with different ammo as it leaves the unfired round stuck. Looking for opinions, from post above it looks like SA is good at addressing issues. TIA
**using spent casings, they will not easily push into the barrel on the EMP, on my other 1911', they drop in, no excessive friction**
