Adjustable grip for a tattoo machine 50 comprising a handgrip portion 20 for the end user to hold during use and adapted to receive a needle cartridge 10, a backstem 40 adapted to engage with the oscillating bar of a tattoo machine 50, an annular clamp portion 25 and a movable collar 30. The collar 30 is movable between a first position in which the collar engages with the annular clamp portion 25 causing the annular clamp portion to grip the backstem 40, and a second position which allows the annular clamp portion 25 to release the backstem 40 so that the position of the handgrip portion 20 relative to the backstem 40 can be adjusted. Moving the grip backwards and forwards over the backstem 40 moves the needles 11 relative to the cartridge body.
