Browning BPCR trigger/hammer issue

[slug]

My rifle has developed the condition where it won't hold the hammer at the cocked position?
Is there an easy fix for this?
TIA.

Don't those have an adjustable trigger? If so the engagement setting needs tuning.
Or maybe some gunk worked it's way into the trigger mechanism.
Otherwise, the engagement edges are chipped or worn and it needs the attention of an experienced Smith.
