And here's the part you failed to mention. "My teammates and I preferred two-stage triggers to shoot accurately at long ranges without the light trigger liability of a single-stage at close range." The author and his teammates would work around the two stage issues for up close work but preferred them for LONG RANGE shooting. Action shooting/3 gun does not involve long range shooting, in fact the majority of shots at a match are 100 yards and less. The amount of longer shots is very minimal.
I guess face shooting dudes in the same room as you are doesnt count eh. Talk about reading comprehension fail or willful blindness. Give it up.
His point is the 2 stage works for long range and just as well for close range. Do you know what CQB is? It is not long range shooting.
