I am 60 years old and expressed to my son in law (a krav maga instructor) yesterday about an interest to learn to shoot. He gave me his first lesson yesterday which was hands on with a training semi automatic pistol. Your article echoes much of what he told me. He also spent time on the parts of the gun and the names of each part…slide, chamber, magazine release, etc. I looked at your article with hopes of a diagram that I could review. He also taught me the way to hold the pistol including finger placement when loading/reloading the magazine. I was hoping for a diagram or short video of that to review. So those are my ideas of what I would like to see. The article is very good and perfect for me to review about calibers.One last question. What does “scavenging after a SHTF” mean?
