Seems a bit long to me, but as some others have said here, it depends on the gun. For a double triggered gun with straight grip, I'm fitted perfected at 15 1/4", and 15 1/2" feels almost as good. 15 3/4" is clumsy for me.
I find a pistol gripped single trigger gun measures "just right" in LOP at 14 1/2" to 14 3/4" (depending on the length of the grip - tighter grip = shorter LOP).
I'm 5'9", built somewhat like an ape with a short neck, broad shoulders, 34" sleeve on my dress shirts. I can't imagine someone close to my size with a 16 1/8" LOP, but if it feels OK and you shoot it well, it is OK.
