Q: Why is the safety selector able to turn to safe regardless of hammer position

A: This is an added safety feature that allows the firearm to be put on “Safe” whether the hammer is cocked or forward.  We believe this is a much safer solution to ensure the safety of our users and will not affect normal use in any other way.
