You did a much more eloquent job of describing the process, and I admit, I may have used some terms, not in the best light of a description, but my whole point of my post, was to try to explain that the Barrel is by far the most important, and at the same time most vulnerable, part of the firing process, by pointing out that it would be the first to suffer, then the slide would be the next to suffer, and only if ever would the breach face or rearward portion of the Simi Auto Weapon, ever show damage, except that because it is part of the slide, would be damaged, and most likely not useable.
