You have your model numbers confused. The M65LS is a three-inch K-frame (six shot) with a shrouded ejector. The corresponding non-LS model is the M65 (unshrouded ejector and far more common with a four-inch barrel though two and three inch barrel models were made)--the M13 is corresponding blue model. The M60 is a J-frame (five shot).What advantages do you get with the Lady Smith? I'd like to get the 36LS and 65LS by winter but wonder is there any real difference between them and the originals i.e. 65LS vs S&W 60 3," 36LS vs S&W 36. Is the trigger lighter or better somehow?
