Robin Annual (1992-) #6

Pulp Heroes continues with this tale in the style of 1930s Western magazines. The Trigger Twins are sprung from the hoosegow by their pistol-packin' sister, a purty filly who'll answer a man's smile with hot lead. They aim to empty Gotham's banks, and when Robin arrives, there's an old-fashioned, lead-slingin' showdown.
