Another Walker adjustment

[M. De Land]

Still learning the nuances of the new Uberti Walker I acquired last year I recently noticed that the trigger nose is contacting the half cock notch as the hammer falls with the addition of the action shield apparently. My guess of the cause is perhaps the added weight on the hammer or possibly interference fit of the shield in the hammer mortise or to heavy of a trigger return spring.
I'll post back with a cause and remedy when I get it all sorted out.
