My experiance with gun's is shorter L.O.P. is easier to adapt too than longer. Long pull's; make ya streach, and it's tough ta find the shoulder.
If it's really short for ya, you'll git hit in the face by your own hand!
You must be a long armed feller with custom gun's ta have 14 1/2" pull.
I measure LOP from "center" of butt plate to trigger,(on the gun).
and; from inside elbow at 90 degree's to middle joint index finger,(like yer gonna pull a trigger
