Trigger shoes are a remnant of the revolver's heyday in bullseye competition. They spread the finger pad pressure on the trigger over a wider area, and give more trigger dontrol. They are meant as an improvement for precision shooting. Trigger shoes are (and have been) a dangerous accessory on holstered guns. Back before the onslaught of liability lawsuits, Bianchi printed warnings against their use in their catalogs, and warned that their holsters were NOT designed for use with guns with trigger shoes. In 54 years of shooting, I have known one yahoo, and heard second-hand of another, who "rearranged" their anatomy by jamming a shoed revolver into a holster. The one I knew personally did it on a Bianchi 5BHL, (open trigger guard) apparently catching the edge of the TS on the edge of the suede lining. On today's politically correct rigs with close-moulded trigger guard coverage, they are an accident demanding its' chance to happen. On a range gun, kept in a case and never holstered, they serve their original purpose well.
