So You Have a Flawless Running Semi-Auto? IISHOT1000 2009

Someone asked a question on another forum and I put this together to answer it. Basically this combines the results of both matches in one place.

The entrants split into 2 neat groups. Guns with 5 or fewer malfunctions and guns with readily identifiable issues that had lots of malfunctions.

Here's a brief rundown of the guns with 5 or fewer malfunctions from the last 2 matches.

• Four guns experienced 0 malfunctions. 2 Glocks, 1 SIG, 1 Colt NRM. 2 using Blazer aluminum, one using Blazer brass, one using Winchester ammo.
  
• Five guns experienced 2 malfunctions each. 2 1911s, 1 Glock, 1 Ruger P95, 1 Springfield EMP. 2 using WWB, one using UMC, one using S&B, one using Blazer Aluminum.
  
• Two guns experienced 3 malfunctions each. 1 Glock 20, 1 Kimber TLE/RL. One using Blazer aluminum, one using a mix of ammo--mostly Blazer aluminum, a little PMC and some UMC.
  
• One gun experienced 5 malfunctions. A Beretta PX4C using WWB. All failures were failures to feed with a single magazine.

In the above guns, the first malfunction was encountered, on average, at round 373.

Here's a rundown of the guns with more than 5 malfunctions from the last two matches. You can see why we stopped allowing reloads after the first year.

In the guns below, the the first malfunction was encountered, on average, at round 20.

• 10 malfunctions (29 projected--entrant left match after 7th of 20 stages)--Springfield .45--Blazer Brass. 1 bad magazine caused consistent failures to feed.

The magazine that caused me so much grief was a wilson combat 10 round. the others were Chip McCormick which were 10 rounders also.

I have since run 125 rounds through the wilson magazine and had no issues on the fourth or first round? Go figure
