Here's the sort of format that should be used when reporting results in the 2,000 round challenge:
Pistol: Smith & Wesson M&P 9
Ammunition: 115 grain Blazer Brass, 115 grain Winchester White Box, American Eagle (115 grain)
Dates of testing: 7/20-7/22
Total rounds fired: 2,470
The M&P used was my primary carry piece at the time. It had several thousand relatively trouble free rounds down the pipe before the three day USTC class where I shot the challenge.
Pistol: H&K P30 LEM
Ammunition: 115 grain Blazer Brass, 115 grain Federal Champion, 115 grain Winchester White Box, 124 grain +P Speer Gold Dot
Dates of testing: Sept. 1, 2010 to October 28th, 2010
Total rounds fired: 2,393
The pistol was purchased brand new in August. The accumulated round count results from taking the pistol through four classes, day 1 of Todd Green's Aim Fast, Hit Fast, the Appendix Carry Workshop, a 4 hour session on the range with Tom Givens, and the 3 day Vickers Advanced Combat Handgun class, in addition to two range trips outside the listed classes.
