Hello Gary,
That one is pretty far gone and S&W will not warranty it,
I highly doubt the lifetime warranty era guns are covered from being left in the weather for X number of years as well.
AS Floridians we are lucky to have access to a free database maintained by the FDLE.
I had a handgun stolen in 1986 and was surprised the serial came up after all those years.
If that gun was reported stolen in FL it will be in the database.
My guess is since there was no magazine it was probably tossed.
You would be surprised how many people want guns to go away for legit reasons as well as nefariouse,
Not everybody sees a handgun as a valuable commodity,
Many inherited firearms are simply turned in at the local PD for destruction by family members that dont like guns, others are buried, tossed into waterways, forrests or simply into the trash.
