That is the reason I ordered my Rigby with triggers offset for a lefty, but lever opening being right-handed. I shoot over ten thousand shotgun rounds each year, and my muscle memory is opening the shotgun by pushing the lever with my thumb....Another concern at the time was that after decades of being a Lefty but shooting right handed actions - worried that I wouldn’t be able to adjust to a true LH action....especially in a dangerous game situation.
I had ordered the Heym 88B in 9.3x74R in the same configuration a couple of years ago.
