Concealed Carry

Mark Shean Sr, author of GUN SENSE, on Amazon.

Brought to you by www.shotgunswitch. com , We replace the original KSG switch, to keep your hands where they belong and your eyes on target!

If you own a KSG shotgun you know that there is a series of numbers and letters instead of  a conventional serial number on it, you may be curious as to the actual number of your gun, I was so I did a bit of research to figure out my guns number.

Here is what I found.

The letters mean a number; A=10, B=11, C=12, D=13, E=14, F=15, G=16, H=17, J=18, K=19, L=20, M=21, N=22, P=23, Q=24, R=25, S=26, T=27, U=28, V=29, W=30, X=31, Y=32, Z=33

You may have noticed that ‘I’ and ‘O’ were not used probably because they can easily be confused for other characters.

You set up the formula below to look exactly as I have put it in red, for every code.

        X 3400 =

100 X          =

 10  X          =

       X          =


Example; Lets say that the code on your KSG looks like this; X2Z28, you disregard the first letter X and put the number 2 in the top column and multiple by 2 in this example, it comes to 6800. You take the next letter, in this case a Z, if you look at the alphabet above the letter Z = 33, put 33 in the second column and multiply by 100. Now take the next number, the 2 again, and put it in the third column and multiply by 10. Now take the last number 8 and put it in the last column and multiply by 1 every time. Add all the numbers and it comes out to 10,128 in this example.

      2   X   3400 = 6800

100  X    33       =  3300

 10   X     2        =   20

   8  X       1      =     8


This would be the actual number of the KSG as it was produced. A low serial number, a first generation in this case. That’s how you figure out what the code on your gun means.

I hope this is helpful. Mark Shean, CEO, Solutions De Innovation LLC, for the KSG.

My new #GUN SENSE book, Rated #1 at AMAZON in the Shooting section!! Good anywhere people and guns are when it comes to safety. Firearm education saves lives, firearm ignorance can end lives.

    Instructions above explain how the code number tells the production number (quantity), BUT how can you tell what YEAR the KSG-15 was built?
    Thank you

    That’s a good question, I don’t think you can. Call or email KelTec they should have that information .

    There is a replacement switch for the KSG, it fits all models/generations and fixes the two issues listed here. The website is http://www.shotgunswitch. com The original switch is 1. to small and hard to find without one of your hands completely leaving the trigger or foregrip 2. the original switch pivots on the screw causing it to back out after awhile, this can cause the spring loaded detent pin behind the switch to be lost, rendering the shotgun useless. Go to and take a look.
