I carry a full size 1911 AIWB every day, and before switching to it earlier this year I was carrying a 2011 style full size AIWB everyday.
Avg draw at 7 yards to an "A" zone is 1.18s last time I collected data, carried in a Keepers AIWB under a polo.
The time is faster than on previous guns, though I feel that has more to do with major changes to my practice regime now versus previous guns.
