As an indicator, my fingertip to fingertip spread is almost 7'. My shoulders are not particularly wide. Using a stock with my measurement says I need almost 18" LOP... I am only 6'4".
I shoot fine with factory stocks on a 101, most Berrettas, Browning BPS, 870s, and so on. A 17" LOP is ridiculous for me.
That number happens to be close because it falls into the range of averages, not because it is relevant.
