I guess that depends on who's doing the documenting:
The HK45 fired its first 31,522 rounds without a bobble of any kind, another pistol-training.com endurance test record. But the mere fact that it out-performed those other pistols tells only part of the story. I do not believe another .45 pistol could fire that many rounds, in that short a time, with that little maintenance, and survive. Anonymous internet chest-thumpers notwithstanding, fifty thousand rounds of full power 230gr ammo through a .45 pistol in eight months is staggering.
