Pistol: H&K P30L LEM (3 magazines)
Caliber: .40
Ammunition: 2500 rounds of Winchester 180gr. "purple box" and 200 rounds of Underwood 140gr. Xtreme Penetrator.
This pistol had approximately 1500 rounds of Federal 165gr. HST through it with no malfunctions prior to "officially" starting a 2000 round challenge.
I shot all 2700 rounds of the challenge over approximately 3 months and have been using the pistol in some pretty rough field conditions including sand/silt and torrential rains.
Zero malfunctions, everything fed, went bang and ejected 100%.
I had too many "stoppages" to count. With my grip and thumb position the P30 slide will rarely lock back on empty, that's just the way it is and my grip works too well for shooting to change it around for slide lock.
