Chris,
The slide would not move forward. I turned the pistol upside down, and pulled the slide back, and eventually the round fell out.
I thought it was the round, or else the magazine. I have been cursed with Hydra-Shoks and in the past have had a specific round that that would not feed in any 9mm.
I'm going to concentrate on Golden Saber, Gold Dot, or Ranger LEO.
My Sig P239 barrel did receive the hard chrome treatment from Tripp Research. I noticed that Teddy Jacobson recommended against doing the barrel, but too late for me.
I'll shoot 150 each of Golden Saber and Gold Dot next week. If everything is flawless, it will go into service as a backup for my R9S.
Bill
