Hey guys, after owning my HK45 for over 7 years, I finally got around to examining the test fire casings included in the box. The casings appear to be nickel plated and inscribed with "45AUTO+P" and two stars with a line between them. The head of the casing was painted red not just the primer. I'm not familiar with this headstamp and was wondering if any of the members could identify this headstamp. The HK45 was an American build. Thanks for any info!
