Beretta does not retain any copies of the paperwork submitted with a warranty registration. In addition, our warranty records are purged on a regular basis of warranty data that has expired. What your insurance company and police department will require, if you no longer have a copy of your bill of sale, is a copy of the Firearms Transaction Record - US Government 4473 form data, that is retained in the original selling dealer's "bound book" entry for the firearm you purchased. Due to privacy regulations, we cannot request that information from the selling dealer. You must contact the selling dealer directly.
In the instance where a dealer may no longer be in business, it is a federal government requirement that dealer surrender their "bound book" log to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) upon retirement from the firearms business. In that case you, as the owner of the firearm in question, would have to petition the ATF for the required information.
