The thickness of a handgun is a crucial factor influencing concealability, comfort, and shootability. There's no single "average" thickness, as it varies dramatically depending on the type of handgun, its caliber, and its design features. This guide will delve into the factors affecting handgun thickness and offer some insights into typical ranges.
Factors Influencing Handgun Thickness
Several key elements contribute to a handgun's overall thickness:
1. Caliber: The Bigger the Round, the Bigger the Gun (Often)
Larger calibers generally require thicker slides and frames to manage the increased recoil and pressure. A .45 ACP pistol will typically be thicker than a 9mm, all other things being equal. This is due to the larger diameter and heavier bullet.
2. Frame Material: Metal vs. Polymer
Metal-framed handguns tend to be thicker than polymer-framed handguns. Polymer offers greater design flexibility, allowing manufacturers to create slimmer profiles while still maintaining strength and durability. This is a significant factor in the overall thickness.
3. Grip Design: Size Matters
The grip's design impacts the handgun's overall dimensions. A thicker grip might accommodate larger magazines or provide a more comfortable hold for larger hands, but this directly impacts the overall thickness.
4. Magazine Capacity: More Rounds, More Thickness?
Higher-capacity magazines often result in a thicker grip. This is because the additional rounds require more space within the magazine well.
5. Internal Mechanisms: Complexity Adds Bulk
The internal mechanisms, including the trigger mechanism and safety features, also contribute to a handgun's thickness. More complex designs may require more space, resulting in a thicker overall profile.
Typical Thickness Ranges for Common Handguns
It's difficult to give precise average thicknesses because the variations are so significant. However, we can offer general ranges:
-
Subcompact Polymer Handguns (e.g., Glock 43, Sig Sauer P365): Often around 1 inch (25mm) or slightly less. These are designed for deep concealment.
-
Compact Polymer Handguns (e.g., Glock 19, Springfield XD-S): Typically range from 1 to 1.25 inches (25-32mm). These offer a balance between concealability and capacity.
-
Full-Size Polymer Handguns (e.g., Glock 17, Smith & Wesson M&P 9): Generally fall between 1.25 and 1.5 inches (32-38mm).
-
Metal-Framed Handguns (e.g., 1911, Sig Sauer P226): These tend to be thicker than their polymer counterparts, often exceeding 1.5 inches (38mm) in thickness.
Important Note: These are general ranges, and individual models within these categories can vary significantly. Always check the manufacturer's specifications for precise dimensions.
Conclusion: Thickness is Key for Handgun Selection
Handgun thickness is a critical aspect to consider when choosing a firearm. The ideal thickness depends on your individual needs and intended use. If concealability is paramount, a slimmer subcompact is essential. If you prioritize capacity and comfort, a slightly thicker handgun might be more suitable. Understanding the factors influencing thickness empowers you to make an informed decision based on your specific requirements. Remember to always handle firearms safely and responsibly.
