I just pulled the 27-2 3-1/2" out of the safe along with my Model 28, 4" Highway Patrolman and it appears they both have exactly the same front sight which is NOT a red insert...it is the 1/8" serrated ramp, Baughman quick draw style. Of course the deep blue finish on the 27-2 is obvious over the matte finish of the HP.
My 3-1/2" 27-2 shipped April 5, 1977 per factory Letter, and the Highway Patrolman Model 28 was a 1974 gun so closer to what you are looking at.

Just didn't want to mislead you.
