I got into this on another thread and wanted to see some discussion on this subject but I didn't want to hijack that guys thread so I'm starting this one . I recently went back and re-read everything I could on the famous FBI-Miami shootout in 1986. What I read about it in the year or so after it happened convinced me to change my HD gun from a 38 Special to a 45. But you know how when you re-read a book or see a movie for the second time there's always something that you notice that you didn't notice the first time around? Well, I noticed a couple of things this time I'd never noticed before in these reports. I think the overall conclusion that the FBI drew from the results of that shootout, was that they needed a better weapon and better ammo than 9mm semi's with 115 grain ammo. I think they got that right, and the result was the 10mm, and later in a redesign, the 40 cal. However, when I re-read the reports a few days ago, I noticed that only three of the eight FBI agents involved in the gunfight had used 9mm's. I noticed too, that 4 of the 5 agents who didn't use 9mm's had 357 magnum revolvers, and one had a 38 Special J frame. The thing that startled me was that none of the agents were firing 357 ammo. All who had 357's were firing 38 Special +P ammo in them, and most of the 357's had 2" barrels as did the 38 Special J frame. I don't remember this ever being brought up as an issue, but the agents who had 357's got neither the power of a 357 cartridge nor the maximum accuracy they'd have gotten by shooting their 38 Special rounds from a 38 Special gun. And the 2" barrels, what's with that? A 6' barrel gets about 25% more velocity from a 38 Special +P round than it does from a 2". Any comments about what the results of this gunfight might have been if the 357's had been loaded with 357 ammo, or if all the agents had had 38 Special guns with 6" barrels?
