Could anyone tell me an exact year of my S&W

[Wearcher16]

I have a S&W MOD 66 (no dash) 357 combat magnum
Serial# 9k 38328
Could anyone tell me the exact year possibly and maybe anything else that could possibly be interesting about this specific one. Possibly a few self defense round options even, im thinking of getting Hornady Critical Duty 135 Grain JHP.

Welcome to the forum. If no one post your date try Smith and Wesson Customer Service

Made in 1977. It could have shipped later, but you'd be safe thinking of it as being from 1977.
