Identification considerations
Use SKU 215921, slide and frame markings, caliber, barrel markings, dimensions, and HK documentation. Compact designation and caliber must both match.
Safety and professional service
A barrel affects chambering, locking, and pressure containment. Keep the pistol unloaded, remove the magazine, verify the chamber is clear, and separate ammunition. A qualified gunsmith should confirm identity, compatibility, condition, installation, lockup, and safe function.
