First off, apologies on the wait on this one. I've been on my back in bed.
Second, I always make the assumption that the person I am speaking with is at least as intelligent as I am. In most cases they are more so. I don't like to talk down to people. Sometimes I make that assumption in error since a lot of it that seems to be perfectly understandable to me isn't to the reader. Apologies again for not explaining my points better.
And here is where where my remark about "you planning to get hit....instead of using the weapon as it was designed and is used by 99.999% of all users..." comes in. You, and the other fellow as well, seem to be under the mistaken impression that standing up square and shooting it out is somehow some sort of new, super intelligent practice. It isn't. It's stupid. Your statement above about planning to take hits on your carrier/plate is, to be blunt, ridiculous. You also don't wear a helmet so you can head butt doors, ballistic goggles so you can watch the bullets coming at you etc etc etc. Your armor is your last line of defense. If it's hit, YOU screwed up! You plan to NOT GET HIT. You maintain your cover. You shoulder your weapon and you stay hidden behind the brick wall to your side. That's a bit hard to do when you're standing square, in the open, and the weapon braced on your chest.
I'd hope you would teach her proper shooting technique....but to each his own. Look up the "Turnipseed Enhanced Weaver Stance System". You'll learn how to shoot a full mag of slugs and buck while ballanced on one foot.
I'm sorry to hear you haven't been well, hopefully not serious.
I'll come back to this when I'm able to give it the time it deserves.
