- Pistol: SIG 1911 Tactical Operations
Caliber: .45 ACP
Ammunition: BVAC 230 grain FMJ, Remington 185 grain FMJ, PMC Bronze 230 gr FMJ
Dates of testing: 15-Mar-11 to 27-Mar-11
Total rounds fired: 2,027
Stoppages: 1*
Malfunctions: 0
Breakages: 0
Notes: The sole stoppage occurred when the slide locked open on a magazine that still had a round left in the mag. The magazine used was an aftermarket Chip McCormick 10 round mag. No stoppages of any type were encountered with factory Sig magazines, Wilson Combat magazines, or Chip McCormick 8 round Shooting Star magazines. Prior to the challenge, the 10-round McCormick mags had occasionally experienced this issue, but I was using them for the Speed Kills/Get SOM class so I could have more ammo on the line at a time.
