Is there a 2-letter date code on the gun? That will tell you the year it was proof tested as a complete gun.

On my 1984 P230, it was difficult to find. Look at the string of proof marks. At the beginning of the string is something that appears to be another proof mark, but turning the gun sideways revealed it to be JE, stamped sideways.

This is what you are looking for. I circled the code in red. This example (taken from online) is KD which equals 1993. (K=9 and D=3)

The codes are as follows:

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