Purchased mine today, detail stripped it, polished a LOT of light tool marks and surface scratches out, properly lubed it and installed grips that fit my hands.
Trigger pull is a bit stiffer than the Gun Blast subject piece, slightly over 6 lbs single action. Didn't try to measure the DA pull.
No markings at all on the left side. Deep, crisp engraved RUGER SP101 and .22 LR CAL on the right side of the barrel with the Safety info and Newport NH on the bottom. Serial number, Ruger crest with black background and the R mark on the right side of the frame. Serial number 577-028XX.
