From http://pistol-training.com/ "50,000 rounds in just over eight months If you’re like me, you’ve been following the HK45 endurance test over at Pistol-Training.com. The test finally concluded at 50,000 rounds and I was honored to fire the 50,000th round through the gun that I helped bring into existence. As expected, the gun passed the test with flying colors and amazingly experienced only a couple of minor problems… all while going 10,000 rounds between cleanings!"
