Great this is the topic I was always embarrassed to ask about. I never understood why most of the side lever guns ( beautiful guns) had lever on right side of action, when it would seem right handed shooters would need it on left side so they could open action with right thumb while holding stock in right hand and forend in left hand? So lever on right side of action was to accommodate a loader standing on my right side( I’m right handed) to grasp the gun with his left hand, open it with his left thumb and load it with his right hand? Anyone have a video of this side lever 2 gun transaction between shooter and loader? Or do I have this thumb thing confused? Never was much of a dancer, I’m sure you understand why!
