Heckler & Koch
The H&K 970173 thread cap for .40 caliber is a straightforward OEM replacement or spare part for shooters running H&K VP40 or USP40 pistols. Manufactured from black steel, this cap threads onto the barrel to protect the muzzle threads when a suppressor or other threaded accessory isn't mounted. If you've lost, damaged, or simply want a backup thread cap for your .40 H&K, this is the factory-correct piece.
Whether you run your VP40 or USP40 suppressed sometimes and bare other times, or you just need to keep threads clean and protected in your range bag, having a quality thread cap on hand makes sense. The black steel construction resists corrosion and blends with the gun's finish.
This is a genuine H&K part—no guessing about fit or finish. If your H&K .40 came with a thread cap and it's gone missing, or if you want a spare, the 970173 is the right replacement.
