Hello,
I just bought one, but I sent it out for a trigger job, so I don't have it in front of me. From what I remember, the safety/decocker is ambidextrus [sp?], but the slide release and mag release aren't. The slide release is EXCELLENT, if you are right handed. I can release the slide after inserting a new magazine with one hand and not 'twist' the pistol so my thumb can depress it. Great pointer and feels wonderful in my hand. I sent it in as my pistol [full sized baby eagle 9mm] had a very gritty da pull. As they install it, I am having Meprolight night sights installed. When I get it back, I'll let you know for certain about safeties: and I'll tell you how I like it from range-work.
