I'm a right-hander that shoots leftie. My guns are all left-handed. Since left hand guns are available, I would recommend the left hand lock versions. It will give you one less thing to think about when you should be thinking about trigger squeeze and sight alignment. Keeping the lock on the correct side is no guarantee you will not get some stuff flying around at the shot. Even with glasses and a ballcap bill protecting my face and eyes, I got hit in the eye so bad one time, I had to go to the emergency room. I still haven't figured out how it happened. Period correct or not, safety glasses are an emphatic must when shooting a ML, flint or percussion. Getting hit in the eye with pan or cap debris may be Period Correct but it is carrying things a bit too far for my tastes. I am always amazed at the number of people, adults and especially kids, who don't wear safety glasses when shooting. Congratulations if any of you have not suffered a flint chip or bit of hot powder in the eye, up to this point. Never fear, though. Your turn is coming. :m2c:
