Looked over your link. Sounds interesting, but I can see some bad habits coming from this in favor of sighting-scoring on target. Many pocket guns have sights (if you call it that) and are utilized for quick shots, short distances at a humans K-zone to disable a BG. Many of us prefer the point shooting (unsighted fire) with our compacts...An example of what I'm referring to...Some time back, Michael Bane on a TV "Guns-Ammo" IIRC, was illustrating firing at an extremely close range, almost arms length. He pulled his pistol in a classic Weaver w/two hand sighted fire and blasted away. I almost fell out of my chair..In reality, the time it took for him to do all this; he was a goner from a knife or pistol attack. I believe he thought he was doing the right thing (might have been at GunSite in AZ); but didn't let his instincts kick in.
