I wonder if anyone knows the actual sequence of events when a recoil operated gun like the 1911 is fired. Is the projectile clear of the muzzle before the action begins to unlock and open? I reload and I was thinking about headspace and cartride length considerations and began thinking about what happens first. visualizing the primer explosion and the powder igniting & burning & the gas expanding and the projectile overcoming inertia as it begins to race out the barrel to exit the muzzle. At some point the slide begins to travel in the opposite direction disengaging from battery and doing it's job of extraction, ejection, picking up the fresh round chambering & coming back to battery. Considering that the slide weighs far more than the projectile one supposes that the time required to overcome inertia is longer for the slide than the bullet response time but it also seems that the realitive movement would begin at the same time with the barrel and slide moving together at first and the toggle link drawing the barrel down and out of battery untill the barrel is fully disengaged and the slide continues through the remainder of the cycle. If the projectile was not clear of the muzzle the action/reaction would have a proportional effect on accuracy. this would tend to cause vertical stringing of shot groups which (perhaps coincidentily) is what I see most at the range.
