How to Read Colt 1911 Serial Numbers: A Comprehensive Guide

The Colt 1911 is an iconic American pistol that has been a staple of military and law enforcement agencies for over a century. With millions of units produced, identifying a specific model or year of production can be a challenging task, especially for inexperienced collectors and enthusiasts. However, reading Colt 1911 serial numbers is crucial to determining the age, authenticity, and value of a particular pistol. In this article, we’ll provide a step-by-step guide on how to read Colt 1911 serial numbers and decode the mysterious codes.

What Is a Serial Number?

A serial number is a unique identifier assigned to a product, in this case, a Colt 1911 pistol. It is typically found on the lower receiver, slide, or barrel of the firearm and serves as a means to track production, quality control, and inventory management.

Where to Find the Serial Number

The Colt 1911 serial number can be found in one of the following locations:

• Lower Receiver: The most common location for the serial number is the left side of the lower receiver, near the butt of the pistol.
• Slide: Some 1911 models have the serial number stamped on the slide, usually on the left side or near the ejection port.
• Barrel: Occasionally, the serial number might be found on the right side of the barrel.

Decoding the Serial Number

Colt’s serial number system is quite complex, with multiple variants and prefixes used throughout its production history. To make it easier to understand, we’ll break down the decoding process into smaller segments.

Prefix and Pre-1932 Serial Numbering

Before 1932, Colt used a prefix letter to indicate the year of production. The prefix system was as follows:

• A (1880-1890)
• B (1890-1900)
• C (1900-1910)
• D (1910-1912)
• E (1912-1920)
• F (1920-1932)

For example, a serial number prefix of "A1234" would indicate that it was produced in 1880.

Post-1932 Serial Numbering

After 1932, Colt abandoned the prefix system and introduced a decimal-based numbering system. Here’s how it works:

• First Digit (1-9): The first digit represents the year of production, incremented annually. For example:

  • 1: 1932
  • 2: 1933
    +…
  • 9: 1941

• Next Digits: The remaining digits represent a unique identifier within the range of that year’s production.

Example: Decoding a Post-1932 Serial Number

Serial Number: 34567

• First Digit (3): indicates production year 1944
• Next Digits (4567): a unique identifier within the 1944 range

Additional Prefix Letters and Special Codes

Occasionally, Colt used special prefix letters or codes to indicate specific features or treatments. Some common examples include:

• S (Slide Lock): Pistol was shipped with a slide lock.
• SC (Slide Lock and Crisp Trigger): Pistol was shipped with a slide lock and crisp trigger.
• T (Trial): Pistol was part of a trial or demonstration model.
• GI (Government Issue): Pistol was produced for the US military.
