You have learned why most people send there pistols to us for warranty. Just because they are listed, does not mean they know of what they speak.
You can use Remington Golden Sabre, or Cor-Bon without any adverse effects on the pistol. If it still acts up, send it to us and we will fix it correctly and get it back to you. Please let us know what you have happen.
Thanks,
