I have a .44 S&W 629-6 (Mountain Gun) with the lock removed.
Remove the grips, back off the main spring screw and pluck out the gizmo.
Takes only a few minutes.
I wonder if in the 1890s, the S&W New Departure "Lemon Squeezer" went through similar criticism for having a child resistant grip?

By the way, it makes a great pocket gun.
