Clearance issue during fitting. With the barrel partially linked down/out of lockup (as pictured), I cannot fit a .010" feeler gauge between the top barrel lugs/hood area and the slide. I’m also getting fairly heavy witness marks on the upper lugs and top of the hood during cycling.
Does this suggest the barrel is not dropping enough during unlock? If so, is the correct approach to slightly deepen/relieve the chamfer on the inner slide rails to allow the barrel to seat/drop slightly deeper, or should I be looking elsewhere first? Thanks!
