Shades of the sniper vs sniper match from Saving Private Ryan, only in this case it was a .45 bullet traveling down the barrel of a .40 calibre handgun....

In an exchange of gunfire that left him seriously wounded, Marquez hit one suspect in the leg, and another of his .45-caliber bullets made a "one in a billion" shot, according to a letter Orman wrote to Jefferson County Sheriff Jeff Shrader and Aurora Police Chief Nick Metz.
That round traveled up the barrel of the attacker's gun, colliding with a cartridge in the chamber and rendering the .40-caliber pistol inoperable, the letter said.
