MK 760. I have one here that I took from the original box that it came new in and hung it on the wall just above a S&W 76. After reading the above commentaries, I will have to field both to see what I get. I do not like Win or Rem hardware store 115 gr ammo (above video mentions 124 gr) . First sub gun I tried it in emptied the mag on its own. Bullets too light .?? Not enough powder.?? It works fine in a Beretta 38, but I suspect the Berettas bolt travels a bit farther. Got away from the subject a bit. We have weather today, but I am still inside the 6 weeks recovery time for a new knee and not moving as well as I hope to be soon.
