Since we're reviving threads, I shoot left handed (almost blind in right eye) but I'm right handed. I bought a new Maxus II last year and changed the cant on the stock and I love it. I don't have a problem with any semi auto rifle, shotgun, or pistol. I prefer to get those right handed for ease of modifications and resale. If you're a lefty wanting a shotgun and don't know which way to go and are okay with a pump, get a BPS.
However, I just picked up my first left handed bolt in 280AI and I really think I'm going to love it. I love reading these threads because I felt so alone before I started talking about it and now realize there's a great deal of people that shoot lefty because of eye issues or just normal eye dominance. Even had to teach myself how to shoot a bow left handed because my eye condition didn't start until I was older.
