I have done this ?Challenge? with my Px4 Compact, and my P07, and been doing it with a Canik TP9V2 (at 1,250 on that one).
The original idea was to identify reliability or mechanical issues, early, before putting a pistol into carry rotation. Once ?vetted? the pistol gets cleaned and maintained as well as possible when it is operating as a carry piece.
I maintained a log book with ammo brands, and types used, and any failures noted during the 2,00 round process. I try to put as many brands, bullet types and weights through, as I can to also try to identify any ammo sensitivity issues or preferences.
In my case the Canik is being put through purely out of curiosity of how this pistol stacks up compared to more generally accepted pistols as CZ, Beretta, and Sig.
