Sweeping around the internet I found this article: The Associated Press: 6 cops, 59 shots, 43 wounds, 1 dead man in Tenn. I'll sum up the pertinent parts. Six officers took 59 shots in three volleys in three seconds with .45 cartridges. I'm not trying to start the old caliber argument found everywhere, but it does raise some concerns in the pistol I'm choosing for concealed carry. I'm looking at the Glock 36 for it's reliability and ease of concealment. I understand most shootouts last less than a minute, happen within 7 yards and usually consist of three shots or less. Looking at this article, maybe 6 rounds isn't enough? A thought occured to me, a perfectly expanded 9mm can be the size of a .50 hit but a .45 ain't gonna get smaller. Any advice?
