I recently purchased a Springfield Armory, XD 45ACP 9611 and have been initially pleased. However, last time out at the range, when i was demonstrating it to an associate, it failed to fire. USING FACTORY AMMO, 230 GRAIN, FMJ. NO MODS TO THE WEAPON COMPLETELY STOCK. I ejected the failed round, noticed no strike mark on the primer, reloaded and attempted to fire again. No joy. I then changed mags; samo-samo. i cased the weapon and took it home for a closer inspection. It did not seem overly dirty and everything else functioned on the weapon. my only observation of anything different was that the firing sequence seemed "not as snappy", or a bit sluggish. I called SA, and they said to check the striker for excess lube because it could be causing a 'hydraulic' which would slow the strike. I observed visible liquid on the striker. I then wiped the striker with a cloth, and reassembled. took it to the range and it fired. I HAVE NOT DONE MY USUAL TORTURE TEST OF 50 RDS, AS FAST AS I CAN SHOOT 'EM. Now, here's my dilemma; I don't lube my gun. How did it get there? Has anyone else had this happen?
