To replace the firing pin in an H&R Topper shotgun, first ensure the firearm is unloaded and safe to handle. Remove the barrel by unscrewing it from the receiver, then locate the firing pin inside the bolt assembly. Use a punch or small tool to carefully drive out the old firing pin, and then insert the new firing pin in its place, ensuring it is seated correctly. Reassemble the shotgun by reattaching the barrel and performing a function check.

Disassemble the derringer according to the manufacturer's instructions, typically by removing the grip and accessing the internal components.

Reassemble the firearm, ensuring all parts are securely fitted before testing its function.
