HK45.
Todd Green of Pistol Forum did and endurance test on one and it went over 31,000 rounds fired before it's first bobble!!

50,000 rounds in just over eight months.
And yes, as many of you have guessed, that is Larry “LAV” Vickers himself shooting #50,000. It seemed only fitting that the man most responsible for the HK45′s existence be there at the end of this incredible test.
Over the course of the entire test, just one single spring broke. The gun is still perfectly reliable and suitable for daily use. Now my wrists and elbows, on the other hand…
In fact, the HK45 had fewer problems at the 50,000 round mark than either of the previous two 9mm test guns, the S&W M&P9 or HK’s own P30! The HK45 truly is bomb proof, especially when you consider that except for two spring change maintenance cycles, every single part in the gun is original. Most companies recommend changing the recoil springs on their 9mm pistols three or four times more often than Heckler & Koch recommends for the HK45.
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.
(Actually, in fairness, it was only 49,880 rounds of full power 230gr. I did shoot 120rd of ASYM 185gr National Match Target JHP. Do you think that’s what made the difference? Nah, probably not.)
So what are the final numbers:
252 total days of testing
96 trips to the range
average 520.8 rounds per trip
392 hours of range time
average 127.5 rounds per hour
The HK45 was fired in nine States… and one foreign country, eh?
Twelve different types of ammunition from nine different manufacturers were used:
CCI Blazer 230gr FMJ: 26,185
Federal American Eagle 230gr FMJ: 21,354
Remington UMC 230gr MC: 850
Winchester 230gr Ranger SXT: 542
PMC 230gr FMJ: 600
ASYM 230gr FMJ Match: 124
ASYM 185gr National Match Target: 120
Black Hills 230gr FMJ: 50
Mag Tech 230gr MC: 50
Pro Load 230gr Match FMJ: 50
Winchester (white box) 230gr FMJ: 50
Remington 230gr Golden Saber BJHP: 25
The pistol was only cleaned seven times during the entire test, going 10,181 rounds between cleanings at one point.
My final thoughts on the gun:
Shootability: Let’s face it, nothing else matters if you can’t shoot the gun well. The HK45 proved far more performance-oriented than I gave it credit for at the beginning of the test. High bore axis? Not an issue. Heavy recoiling 230gr hardball? No problem. Sub-2 second Bill Drills from concealment? Hell yeah:
