What does "length of pull" refer to in firearms?

"Length of pull" refers specifically to the distance from the trigger to the end of the stock. This measurement is crucial for achieving proper fit and comfort for the user. A correct length of pull ensures that the shooter can maintain a proper stance and achieve effective control of the firearm while aiming and shooting. If the length of pull is too short or too long, it can lead to improper shoulder placement and can negatively impact accuracy and comfort during use.

The other options do not accurately represent the concept of length of pull. The distance from the muzzle to the end of the stock focuses on the overall length of the firearm, which is not the same as the shooting position and ergonomics. The overall length of the firearm also encompasses the entire structure, including the barrel, rather than just the trigger area. Lastly, the length of the barrel is a specific measurement related to shooting dynamics but does not relate to how the shooter interacts with the firearm through the stock.
