I see what you mean. Revolvers apparently don't need all that slide weight to make them work. And revolvers don't soak up any of that recoil like a locked breech style.

East of Nokomis. Know that area very well. Used to hang out around their a lot many moons ago. from the early 60's when I was a boy until I got hitched. Late 70's.
I was from closer to Lake & cedar. Poor side of town!! I did attend Rosey tech for a spell back in the late 60's early 70's.
