the reason I started this thread was to get the final answer on 9mm vs 40 S&W, it looks to me like the handgun cartridges of choice had little effect on the the outcome and if the 40 has been used probably wouldn't have even mattered. but double stack mags in say a full size glock would have made a big difference.
it was a different time back then and reliable semi autos were just coming on the market. yeah the 1911 was reliable at that time but only with ball ammo and as a result never caught on with LE agencies. the real problem like everyone is saying is rifle fire against pistol fire.
