I have changed several out because I am lefthanded.The factory replacement is not reversable but I am pretty sure the after market safeties are reversable.I use to get the giant head safeties for about 15 dollars. I will try to explain from memory.It has been a while since I done this.Pull the slide back untill it locks open.Than drive the 2 round pins out of the reciever.This should allow you to pull the trigger assembly out.This is where it gets a little fussey now.But I think I remember there is a small pin you have to drive out to remove the safety.Be careful and don't loose any parts.There is a small plunger involved.If you have the kind if safety I think you have you should be able to reverse it and put it back together.If you don't want to try this a gunsmith should be able to do it for you for a small fee.
