Just curious, why would you need a new spring for the LCR? My gosh, they are, out of the box, one of the nicest revolver double action triggers made. The friction reducing cam makes them even feel lighter than they are.
I swear to god they put rimfire springs in the lcr .327’s. I’ve dry fired a couple.38 versions, and they’re def at 10 lbs. my wife’s.327 version has a horrible heavy trigger.
