Are you using a specific graphite or something like you'd pick up at the locksmith shop?
You're the second person to suggest graphite.
I'm going to pull the bolt down in the next few hours and I'll follow up. I'll probably remove the trigger assembly and run it through the ultrasonic also.
Lighter fluid on the trigger too
I think I got my graphite at Ace. I read quite a few guys run their assembly dry.
I got some new stuff that's a dry graphite spray I run on my pistols that I like most bigly.
And if it doesn't help or you're uneasy TriggerTech makes nice stuff, lol.
