For years, I carried a J frame .38 with one speed strip for a reload, and I never felt at a disadvantage. Now, I also have a G-36, S&W M&P 9C and a S&W BG-380, and my sidearm varies based on what I'm wearing and how deeply I must conceal. In my last concealed handgun recertification course, the instructor said we should all carry a high capacity semi-auto with two spare magazines. I know a lot of semi-auto failures are caused by mag issues, but he was speaking in terms of what was needed in a gunfight. From your experience, what is the average number of shots fired by a civilan in a self defence incident, and what's the most shots you've heard of that a civilian has had to fire? Thanks.
