Having watched a lot of First48 and various prison/jail themed shows, I would begin any discussion regarding murder in particular as not well thought out. I see very little in the way of Mr Brooks and a whole lot of drunken/stoned impulse driven shootings.
My bet is most criminal acts of this kind occur with no planning and with whatever firearm the person may have been able to afford. It would appear that the most common firearm used is a 9mm auto.
You are correct. The world record 8 shots per second (480 rounds per minute) were extremely accurate shots. The world record 12 rounds in 3 secs (240 rounds per minute) were also extremely accurate shots. It appears the record was for both speed and accuracy.
Semi and full auto pistols can cycle over 1000 rounds per minute. Approx 17 rounds per sec.
That leaves the door open for someone to beat the existing world record using an auto-loader. Both revolvers and pistols experience muzzle jump and barrel torque, so that’s a wash. Pistol shooters have the moving mass of the slide to compensate for and higher magazine capacity would mean fewer stops to reload.
The auto-loader will cycle faster but now I wonder if a world record shooter would be able to bring the pistol back on target fast enough and be equally as accurate? Interesting question.
Oh, and to keep this post on track with the OP, criminals will use whatever weapon they can get their hands on. Auto-loading pistols are currently more popular.
We were trained that if facing a revolver and all other options failed to simply grasp the cylinder and twist a revolver out of the shooters hand. I, nor anyone I knew put this tactic to the test. I believe that if the hammer is already back even that game is over.
I the wise words of Mr. Slim Charles, “(a revolver) don’t hold fi’teen”. And even with a speed-loader, for the average user switching mags is going to be faster than emptying a revolver then filling it back up.
If you’re worried you might get into a firefight, or are a spray-and-pray type of shooter, that’s a factor to consider.
This came into play for a case where I was on the jury, 1st Degree Murder. Gang-related, but the guy that got killed was an innocent bystander.
The defense tried to cast doubt that the location of the found casings was consistent with the prosecution’s accusations. We, the jury, could tell (or we were advised, I forget which) that the casings would have been thrown some distance, and we decided that they were incriminating.
That trial was certainly an educational experience, but one that I never want to repeat.
