Trigger problem on Lyman Great Plains .54 Cal.

[Forrest Smith]

I acquired an older Lyman "Great Plains" .54 Cal "Kit" rifle. The double set triggers only worked, when the "set trigger" is set/engaged and then the front trigger pulled. Using it as a single trigger only, the trigger will not release and thus not let the hammer fall. Has anyone else run into that problem? (When it arrived, it did not have a set screw for the double set trigger arrangement. I located a set screw and put it in.)

Did the former owner remove metal from the top of the forward trigger?

That I do not know, I will have to pull it out and check. But not having another one to compare to, I might not be able recognize if he had or not. I will take photos over the weekend and post it for everyone to look at it.

Sounds like a good excuse to go buy a deer slayer trigger.

I second the Deer Slayer Trigger. I had issues on my GP 50cal, either the set trigger wouldn't hold or the front wouldn't release.

This description is throwing me off.

What do you mean "the trigger will not release"?

Are you trying to fire the gun with the front trigger without setting it? When you pull that trigger does it come into contact with the sear arm?

This can be a matter of geometry. The trigger mechanism may be too far forward. The sear spring may be too stiff.

I've seen several GPRs that had extremely heavy front triggers. In the 20# plus range.
