Can a loose fitting barrel link at the slide stop pin hole cause incorrect timing during linkdown?
Lets say a 1911 is setup to link down with the slide at 0.25" aft of battery. When hand cycling the pistol at slow, controlled speeds, the barrel has linked down sufficiently (0.012" to 0.018" clearance from top of barrel above the chamber to bottom of slide lug). In this scenario, the slack from the link pin does not come into play because the slidestop pin "rides" the contour of the barrel's lower lugs.
However, when the gun is fired, the barrel (initially trying to go forwards) is forced backwards by the slide and the link swings the barrel downwards. In this condition, the slack is taken out of the link by the inertia of the barrel, and the radius the barrel swings down at is larger than it was during the hand cycling. Let's say that the slack is enough to cause this condition to have nearly zero clearance between the top of the barrel and bottom of the slide lug.
Has the slack in the link caused a mistiming? Thanks for helping out a confused individual.
