What two letters are stamped on your slide?

KH, KI, KK, AA, AB, AC, etc......

A=0 so AA is 2000
B=1 so AB is 2001

Follow the formula

[uncut]

just remeber there is no "J" on the date code for the guns

A = 0
B = 1
C = 2
D = 3
E = 4
F = 5
G = 6
H = 7
I = 8
K = 9

sooo it should all make sense now
