Looking for an LOP benchmark before I cut the stock for my daughter.

Based on my crude method of "fitting" I am planning on cutting it down to 12-7/8".

Her height to weight ratio is pretty normally (not overweight), along with arm and neck length.

Thanks...gbt
 
From Dennis DeVault's October Newsletter:

Another item to add to the confusion, what is the LOP (length of pull) of the stock? Today we
have triggers that slide back and forth so if you are measuring the LOP from the trigger what number
do you want it to be. I can vary the LOP up to a 1/2” depending on how far the trigger will slide. The
slide was created to adjust the grip distance for the trigger finger and has nothing to do with the LOP
of the gun stock.

This single statement has caused for much confusion and fireside chats at the local gun clubs
as to what is the LOP of the stock. Since all this has happened we no longer take the dimensions
from the location they have been taken from for many years. Now when we fit a stock to a customer we simply look at the opening of the elbow joint to determine the proper LOP of a stock. Once this has been established we give the customer that measurement with a reference to the current location. If later the trigger is moved the LOP measurement will be changed but the length of the stock is still the exact same stock that is there so the numbers give a false reading and no longer have a relevance to anything. Today with all the adjustability that have been placed at the shooters hands we have to begin to change the way measurements are taken and what they mean. It is impossible to take and give hard numbers and units of measurement to an object that can be moved.
Lets take a closer look at what has been presented here. If I take a stock that has a current
LOP from the front edge of the trigger to the center of the recoil pad in the rear of the stock and for
the sake of numbers that measurement is 14 1/2”. Now if I take the trigger and slide it toward the
rear of the housing and take another measurement. Now that measurement reads 14 1/8”, did
moving the trigger change the stock and how it fits into the shoulder pocket of the shooter? Answer “NO” it is still the same stock as before and nothing has been altered except the grip distance. That is the distance from the inside radius of the grip and where the finger hits the center of the trigger. So in
the future when selecting a new or used gun the numbers that are given are just that a number. If
the trigger is adjustable you will have to shoulder the gun to be sure the length is correct.
To determine that we now use the bend into the elbow to determine the LOP. What you need to look for is about a 40 to 45 degree bend at the elbow. If you are stretched to far the elbow will be somewhat straight. If you are right handed and attempt to move right the stock will get jammed and roll your face out causing the shooter to come out of the stock. Your face will lose the contact necessary to keep the face in line with the stock. It will also cause you to short shoot your right angle targets.
 
I would suggest you go to a stock fitter instead of possibly cutting the stock and ruining it. Fitting a gun is not really an amateur/DIY project unless you have done some in the past. JMO
 
As per Garry & Dennis D. info, when my wife (5'2" with small hands) was shooting I made a stock for her 1100 that had a short pistol grip. Did this to keep\move her hand forward to have good trigger feel\control. Don't remember the exact stock length but it was shorter than factory. Ross Puls
 
Another thought on the subject.

My sister in-law (a first time shooter who I took out a few weeks ago) looked awkward trying to mount and shoot a Remington 1100.

I gave her my Beretta A400 and it looked like it was made for her.

Both guns are at 14.5.

Something more going on there then I'm aware and above my pay grade. Maybe height of comb, height of pad.

Anyway, there is a person in Quebec who has been doing gun fittings for at least 40 years. As a youngster he trained in Germany and then immigrated to Canada.

I'm sure he's like many who have been doing it for years.

He has you mount your gun, he looks down the barrel and within seconds he tells you what you need done. Out comes the chop saw and then a trip to the patterning board. He may also shave a little wood where wood and metal meet.

Obviously, a basic fitting and if you need comb work, you will have to leave the gun and come back.

$$$ well spent seeing someone who fits guns for a living.
 
Shooters stance and position of upper body when attempting a shot at the triangle of target presentations from each station also plays a part in LOP.

Dennis is right with the angle of the trigger hand elbow! (The hand that controls your shotgun) When a shooter must stretch to reach the trigger, the shoulder muscles will bunch tighter. Recoil pounding on a bunched or flexed muscle makes for a long day of shooting. Shooters will sometimes say, they run out of gas toward the latter part of the hundred targets? Might that actually be due to flexed shoulder muscles, from an improper LOP, rather than running out of gas?

A proper LOP is much more important than most allow and I feel the distance between the trigger hand thumb and your nose is irrelevant. It is what it is when the LOP is correct for the shooter. Other measurements also play a part in a fitting equation to have a fitted to you stock.

What type of gun?
If possible buy a used stock off the classifieds here or eBay.
Then cut away. God forbid even go nuts with Bondo auto body filler to get the grip and comb where you want it.
Or if you are a good wood worker epoxy in splices to add wood to be re shaped.

Then when she grows or gets a new gun, you put the old one back on and sell as a nice used shotgun.
Not a cut down fits only one person special.

Been there done that.

Enjoy the process. It is a learning curve that will result in better shooting and a great time with your daughter.

My wife is 5'2". The factory fitted her at 13" on her Syren with them doing the fitting.
