The only difference I can see is cosmetic - round barrel vs octagonal. I dont have a scale to compare weights; but just hefting one of each I don't notice any appreciable difference. Kinda like the '51 vs '61 Navy. I've always loved the '51; great balance, natural point shooter, looks good - but, I shoot a pair of '61s all the time now. They balance and point just like a '51, they just look sexier. I'm hoping that once I get these L&Rs worked over & tuned for SASS matches, they'll be as good as my '51s and '61s.
