A biopsy device comprises a housing carrying a stylet is telescoping register with a coring cannula and a specimen length adjuster operably coupled to the stylet to move the stylet relative to the coring cannula to set the size of the biopsy sample to be collected. The coring cannula is moved over the stylet and rotated relative to the stylet to excise the biopsy sample from surrounding tissue. A trigger assembly is provided that includes a release button on opposing sides of the housing as well as a rear trigger button that enables a user to comfortably actuate the biopsy device using any of the three trigger buttons.
