S&W participates in "ATFs Access 2000 program", which establishes electronic links with ATF and enables high-speed tracing of your guns.
The price that you paid for the pistol had a hidden 1% tax that went to the NEA.
Purchasing the gun made your actions with it the business of both S&W and the ATF. As shuch you are legally bound to adhere to any product recalls and or modifications that they deem necessary after you purchased the firearm.
S&W Provided quarterly sales data to the ATF. This information included the complete gun sales records that you filled out when you purchased the gun.
S&W with the ATF have a "security Plan" for securing YOUR Firearms if for some reason you are judged not worthy of owning it.
