I'm pretty average height so I'm guessing most people would want a shorter LOP, but I don't hear of people cutting their stocks that often.
I figure I'm about average height (5'11") for a male, and most long guns (shotguns and rifles) fit me about right. However, as I've mentioned before on THR, except for the "youth model" 20ga pump shotgun my 5'1" wife has, she's had to have the butt stock shortened on almost every long gun she's ever bought over the years. And that's been a
lot - my petite wife has been into guns, shooting and hunting since she married me nearly 54 years ago.
Other than her "youth model" 20ga, the only other exception to the, "Get a new rifle or shotgun, have the butt stock shortened." rule for my wife was the Ruger American Rimfire I bought for her for her birthday a couple of years ago. She specifically told me she wanted the Ruger American Rimfire with the component stock so that she could change out the components herself to make the rifle fit. And she did - that little rifle fits my wife perfectly now.
Does the resale value take a big hit if you do?
I reckon the resale values of my 5'1" wife's long guns
do take a big hit when she has their butt stocks shortened. I know I wouldn't pay as much for a gun that I knew I was going to need a new stock installed on (or figure out a way to lengthen its current butt stock) before I could use it.
On the other hand, even though both my wife and I have bought, sold and traded off a lot of guns over the years, I don't think either one of us has ever acquired a gun we didn't intend to use. And modifying a gun (no matter what kind of gun it is) in order to make it fit is just part of the cost - both the "up-front" cost of doing the modification(s), and the "hit" to the resale or trade-in value of the gun.
BTW, I've shortened the stocks on a couple of my wife's long guns myself. I don't like doing it. Woodworking is another one of my hobbies, but I'd much rather leave
that kind of "woodworking" (shortening rifle and shotgun stocks) to someone who does it for a living.
