How to Measure Length of Pull on a Shotgun?
When it comes to shooting a shotgun, the length of pull (LOP) is a critical factor in determining the fit and effectiveness of the shotgun. In this article, we’ll delve into the importance of LOP, how to measure it, and some tips on finding the optimal fit for your shotgun and body.
What is Length of Pull?
LOP stands for length of pull, which refers to the distance between the trigger and the bottom of the comb or the recoil pad. This is a crucial aspect of shotgun fitting, as it affects the shooter’s ability to accurately shoot, comfortably handle the gun, and prevent injury or damage.
Why is Measuring LOP Important?
There are several reasons why measuring LOP is essential:
- Prevents Fingertips from interfering with the shotgun’s firing mechanism: Too much length of pull can cause fingertips to obstruct the trigger, making it difficult to pull the trigger without interference.
- Eliminates unnecessary stretching and strain: Excessive stretch or strain on the shooters’ shoulders and back muscles can lead to fatigue and discomfort, negatively impacting performance.
- Optimizes the shooting stance and balance: Correct LOP allows for a more relaxed shooting stance, better weight distribution, and improved control over the shotgun.
How to Measure Length of Pull
Method 1: Use a Customized Tape Measure
One of the most common ways to measure LOP is to use a customized tape measure, such as one with millimeter graduations. Place the tape measure around the receiver or magazine tube of your shotgun, with the ends meeting at the end of the comb.
Table: Measuring LOP with a Tape Measure
| Length from End of Comb (MM) | Suggested Age Group/ User Type |
|---|---|
| 305-327mm (12-12.9 in) | Youngsters, youth competitors |
| 330-355mm (13.1-14.8 in) | Adults with shorter reach, beginners, casual shooters |
| 365-400mm (14.5-17.4 in) | Average-height adults, intermediates |
| 435-450mm (16.3-18 in) | Taller users, expert competitors, custom shooters |
Method 2: Use a Shooters Length of Pull Tester
For those without customized tape measures, a more affordable and accessible option is the shooters Length of Pull (LOP) tester. These testers consist of a gauge attached to the comb with markings for LOP length.
Tips for Ensuring an Accurate Measure
To ensure an accurate LOP measure:
- Use standard, flat-top surfaces as the reference points (end of comb).
- Keep the tape measure taut but not stretched.
- Record multiple measurements and adjust accordingly for comfort and ergonomic fit.
Adjusting for Custom Fitting
Finding the optimal length of pull requires balancing the needs of shooters with different body types, heights, and shooting stances. Some factors to consider:
- Receivers of varying sizes, especially between shotgun manufacturers (e.g., Beretta, Remington, RemChokes).
- Combinations of adjustable elements, such as stock or comb.
- Alternative recoil pad styles, high-quality foam or gel-foam options.
In conclusion, measuring the length of pull on your shotgun is a straightforward process with multiple methods, ensuring you get the ideal fit for optimal performance. Experiment with different fitting options and consider consultations with a qualified firearms expert, gunsmith, or range officer for custom advice specific to your needs.
We hope this comprehensive guide illuminates the world of length of pull on shotguns and empowers you to achieve the right fit, whether for competitions, recreational shooting, or everyday self-defense. Whether you’re a seasoned pro or just starting your shooting journey, LOP matters; it’s crucial for maximum effectiveness, comfort, and precision when shooting a shotgun.
