Gentlemen,
I've got a question for the community, I've got a No1 in .243 winy and I'm not sure of whether it's an adjustable trigger or not. I'm aware the newer ones are not adjustable. However, my rifle was Manufactured in 77 or early 78.
If anyone has a picture of an adjustable trigger in the rifle with the buttstock off, I'd appreciate it. Also, I'm told Ruger had instructions for the adjustments in the early manuals.
Thank you in advance for your time, help and consideration.
