Reading colt serial numbers can be hard for people who are not experienced. These codes have a slight impact on the firearms, but they are the best way to trace down the origin of guns.
The closest to the mfg date would be stamped on your factory plastic bag that's wrapped on your carbine. Like what member AMMOTECH posted go to the Colt site, Customer Services tab, then click Serial Number Lookup, but sometimes it won't have the info because the info are not loaded in their database yet. Posted: 8/11/2013 4:15:53 PM EDT. Colt saa date of manufacture by serial number. First, identifying a Colt revolver can be frustrating because beginning in 1840 Colt always started each new model at serial number 1, and progressed upward until the model was discontinued, OR until the mid-1960's when the serial number system changed to meet Federal law Serial Number Lookup. The code I'm just assuming is the serial number prefix letters at the left side of the numbers of the serial numbers, in your case with the LE6920 is prefix letter 'LE'. On Sporter marked SP6920 (and other variants) model the prefix letters is 'SP'.
Colt serial numbers contain the history of every gun, but detecting them accurately is a bit hard.
If you are looking forward to learn reading colt serial numbers for the first time, then this article may have something beneficial to offer you. Read below to know more!
Reading Colt Serial Numbers – Here’s How!
There are many techniques that you can follow to find the meaning of a colt serial number. However, some are damn easy and quick, and some are freaking hard. In this written piece, we talk about the comparatively easier ones, okay?
The Quick Method
This one is the easiest way to read colt serial numbers, and all the credits go to the advanced technology. Just head over to the “Colt” homepage and click on the “Customer Service”.
Right after clicking, you will see an option appearing as “Serial Number Lookup”. Click it, and enter your serial numbers. Wait for it, and Bingo!
It is the easiest and quickest possible way you can read a serial number.
However, I don’t prefer this way; the best way is learning to read the numbers manually. Because this easiest way often doesn’t show the accurate result.
The Reliable Method
This method will cost you few dollars, but guess what? It’s the most trusted one – the reliable method. Colt offers a research service to their customers which provides the brand’s official archive letter as a proof of the gun's history.
The letter will have all details of the firearms including genuine features, and specs along with delivery address as well.
Mainly, the archive letter carries essential historical information which can enhance the collective value of that firearm.
Though some custom modifications like the barrel, changed caliber, aftermarket engravings, and finish would not come included in the letter.
As I said earlier, to get this service, you will need to spend few bucks. For your information, the fee is around a hundred dollars in most cases, but again, it depends on the guns.
For example; stuff like the 1851 Navy, you may need to spend couple hundred dollars but it will worth the greens.
Prefix & Suffix
Don't run for a grammar book.! This method has nothing to deal with your Oxford's Dictionary. Mostly, colt numbers contain abbreviations of the firearms’ name. Therefore, you may find some of them are easy to understand.
For example;
- NF means New Frontier.
- MT means Match Target.
- SA means Single Action.
- SP means Sporter.
Capital “C” prefix or suffix on the gun means that is for commercial use, but sometimes these characters indicate the manufacturing year. Confusing, isn’t it?
Model Codes
Checking colt model code is worth the time and effort as they hold lots of information about a particular gun’s history.
The ability to understand these codes will let you know some important features of your gun inside the holster.
Like, the Single Action model of a colt usually has one prefix character and four digits, where prefix shows the frame type and digit indicates the barrel, stock, version, caliber, etc.
The first digit of your gun’s model code “1” means, a basic frame with the first model, and “2” “3” “4” are the later versions of the gun.
The second digit of the model code refers to the weapon’s caliber, like;
- 4 means 32 to 20
- 6 means .357
- 7 means .44
- 8 means .45
- 9 means .44 to 40
The third digit shows the caliber of the gun, such as;
- 1 means 12 inches
- 3 mean 3 or 4 inches
- 4 mean 4.75 or 5 inches
- 5 mean 5.5 inches
- 7 mean 7.5 inches
The fourth and last digit shows information about the weapon’s finish or stock. For nickel and blue finish, “1” and “2” means nickel or blue casehardened finish and 6 specifies nickel finish.
To conclude, reading colt serial number can seem tricky and little tough. This article will give you a basic sense of reading colt serial numbers. And, let’s face it, wordy articles won’t help much than any visuals in learning to read colt serial number.
Consider watching at least a couple of videos on YouTube, or meet your fellow gun geek friend or neighbor next door. This way, you will have lessons that are prone to engrave in your brain easily.

1. There were some odd variations and some custom serial numbers mixed in thru the years also. And, some receivers manufactured after the ban have the year stamp after the model name, not in the serial #. And if you don't see a year stamp on the receiver, it is not necessarily pre-ban.
How To Check Colt Serial Number
2. Serial numbers that end in 'D' were duplicates and one was changed using this letter.
3. Recently some serial numbers have left with one or two letters followed by FIVE numbers. The last numbers are either 5's or 0's. 99.9% of these are post-ban.
4. 'Older' does not always mean pre-ban as per Corey Sattler.
5. 'BL' serial number series lowers are transitional with some pre and some post ban. If you have a 'BL' you'll have to call to verify for certain.
