That leaves safeties. I have hunted with right handed safeties on borrowed guns many times, and while I don't like it, I have gotten by. Some left-handed shooters can reach under a trigger guard with a finger and click off a right handed safety so fast they come to prefer that method, but I want my safeties reversed. Not all guns do reverse easily. The best are the Browning Maxus and Gold safeties, which can be changed in a minute. Old-style Beretta safeties are easy to switch, and Benellis aren't too hard (props to Benelli for making more left-handed guns than anyone else, even though my Benellis are right-hand models). Remington 870/1100/11-87 inexplicably require the purchase of a different safety button, and some guns (Remington 887 and the otherwise excellent Weatherby SA-08) can't be reversed at all, which pretty much rules them out of my consideration.
