RE: left handed guns
If you are lefty there is no reason not to go to a rifle or shotgun. 35 years ago we didn't have a heck of alot of choices, now we do.
While I agree a shell ejecting on the right side shouldn't bother one's shooting there are other issues that should be considered. Ease of operation and fit.
Position of safety for ease of use ,why buy righty and have to spend money to switch it over ? Loading and unloading and more importantly firearm fit. If you're lefty go with a firearm made for the southpaw. You won't be sorry.
