Some insight: ...all of the various rounds used by the FBI in this incident, including the pistol round that was adopted WOULD NOT penetrate the slanted windshield of a same model Monte Carlo used by the perps. The ONLY ROUND that DID penetrate was the .45 230 gr. hardball!
And how exactly is this relevant?
In the first place, the FBI agents at the Miami gunfight did not at any time attempt to shoot through the windshield of any of the cars involved. Their shot opportunities were through the open driver's window of the Monte Carlo, or at Platt as he exited the vehicle (during which he took the lethal hit from Dove's 9mm) or as he moved around the vehicles.
In the second place, if we're discussing current ammunition for current weapons such as a new military sidearm, the ammo offerings in 1986 are irrelevant. I've been present for T&E of many modern service caliber rounds, and aside from the .380, just about any 9mm, 357 SIG, or 40 S&W service round will reliably penetrate angled windshield glass and perform to FBI specs in gelatin thereafter.
