I am left handed, and despise the barrel selectors like the one in the M21 and SKB's or any others which are in the trigger blade. I had one gun with a Miller trigger and the barrel selector on the safety and liked it very much, as it was equally handy for either right or left hand use, and required no extra manipulation. The only other selector that is as easy to use is the one on the Remington 3200 O/U.
