Guys, just picked up my new SBE II. I bought a right handed model even though I'm a lefty as that's what I've been shooting all my life and I'm most comfortable with them. My question is how difficult is it to reverse the safety to Left hand? Is that something I can do myself, or do I need to find a gunsmith to do the work? Does anyone have any experience in doing that and maybe be able to provide some guidance?
