The Daystate Merlyn (c. 2009?) has a white split tubular guide about 2cm long on the hammer spring. I am pretty sure that my hammer spring has been rubbing on the guide at the end of the cocking stroke (spring expansion) to produce a certain graunchiness to the stroke. I have removed the guide and, so far, the graunch has gone. Question: Is this guide essential? I have chamfered the ends of the guide and smoothed the interior in case I need to replace it but do I need to? The spring locates quite happily in a recess in the safety holder and in the hammer housing.
And before you ask, I tried all other means I could think of bar stripping the trigger to try and remove graunch.
Cheers, Phil
