Problem #1 Like most folks in their “early” fifties I started to have difficulty seeing things as they were in the past as my eyes age. I found that my eye was not picking up the front sight on presentation but rather grabbing the rear sights immediately then forcing me to transition to the threat and then back to the front sight. This proved slow and it is not what we teach… i.e. “FRONT SIGHT FOCUS” and it is slow.
Firearms are tools. Very expensive tools which have exacting tolerances, and which are subjected to extreme environmental conditions. Every single actuation of these tools subjects certain parts of the tool to thousands of pounds per square inch of pressure, hot gas, and high impact. Not to mention dirt, dust, grime, and filth from the field. Unbelievably though, I still meet shooters who swear that they abuse their guns right out of the box to test “reliability”, or “durability”. Would they do the same with a $300 DeWalt miter saw or framing nailer? I doubt it. They want their tools to last!
