[digression]I am kind of a "word guy" A few years back, while I was kept low by a bout of sciatica, I made an arrangement with Gerard Henrotin whereby I proofread "Luger Mechanical Features" and edited his text/descriptions to polish up the English a bit and re-phrase some of the descriptions slightly, to make stuff more accessible. He said it was his first Luger e-book, back when he was newer to the language. I find it kind of fun to attempt to make clear technical descriptions, and I think I succeeded. The process also helped me get the Parabellum's action down cold. Once the mechanical arrangements are understood, it's a little easier to remedy issues in function!
