Weird! I've never had a problem with Speer Ammunition, but then again, it's been a long time since I've used any, preferring to shoot my own Match reloads.
With the Barrel out of the Pistol and Clean, do a plunk test on a loaded round of the Speer Ammunition. The Cartridge should drop into and out of the chamber without any resistance.
Otherwise, I would have to see your Pistol at a Range to really know what's wrong with it. It does sound like a weak Extractor Spring, though.
Thanks for replying. When I got home I did plunk and spin test on all three brands and they slid in and out easily, but I still polished the chamber with Mothers Mag polish. It looks like the Speer Lawman case expanded just a hair more and is not as elastic as the American Eagle or Magtech. That was not the case, see my next post. The extractor claw looks great and the extractor spring grips the round very firmly, and easily passes the vigorous shake test (unfired round).
I'm not too worried at this point since it ran the American Eagle and Magtech just fine. I just like all my guns to run perfectly with any ammo.
Also, I just got off the phone with Tristar, and I asked them about the expected recoil spring life, and he didn't know (parts guy). Online, someone posted the interval at 2500rds, but I couldn't verify that. I'm at ~3500rds with the original braided recoil spring. Anyway, my C100 is out of the five year warranty by
less than one month, but he is sending me a new recoil spring, compliments of Tristar.
