This came up two days ago at my LGS as I looked at a S&W 1006 that I was considering.
The salesperson had never heard of that shootout, the FBI adoption of the 10mm, the reduction in the 10mm velocity to "FBI Load", and the subsequent creation of the .40S&W.
They wanted about $400 more than I was willing to pay...

The salesperson found the 1006 to be too big for her hands...even though her carry gun was a 1911! So, we ended the conversation about the cartridge with this: because that gun was too much, the .40S&W was created.
Still looking for a good example of 1006.
I think the other important factor in this shootout was the determined, well-armed adversary. The two criminals were both Army vets, armed with long guns (Mini-14 and 12 gauge, I think), and continued to fight despite being hit several times. One of them was mortally wounded (bullet collapsed a lung, and he would eventually die from this) and both were hit several times, but they continued to fight and return effective fire. Neither was on drugs or had any chemical reason for their tenacity, they just continued to fight.
Despite the agents outnumbering them 4 to 1, and despite the agents having shotguns, they fought effectively, and killed two of the agents.
