I thought this was a good video and enjoyed it. I have a Ruger SP101, shield 45 and LCP custom that gets carried depending on where I'm going and what I'm wearing. Used to have a M&P 9 Compact (wish I still had it). If it's the SP101 it is loaded with 38s.
In regards to the video, the power of the cartridge is really not a factor for me. I feel like the 38 or 9 will get the job done. On the accuracy, I feel comfortable shooting any of the guns mentioned above so that is not really a factor.
Regarding reliability of an autoloader vs a revolver. Revolver would be my choice. In the end though, the determining factor for me is capacity and reloading. So my choice is an autoloader most of the time. Although it is very unlikely that I will ever have to use my gun and even more unlikely that I'll need more than 5 rounds... with the way things are today in this world, I feel better with more rounds and a quicker reload...
