A writing instrument includes a barrel, a refill assembly, and a refill plug assembly that is quick to release from the barrel and quick to re-attach to the barrel when changing a refill assembly. The refill plug assembly is quickly secured to the barrel of the writing instrument and quickly released from the barrel of the writing instrument through a twisting and/or pushing action that may require less than one full turn to disengage from the barrel and to re-attach to the barrel, thus expediting replacement of the refill assembly.

A writing instrument having a selective engagement mechanism includes a first barrel portion with a writing tip and a second barrel portion. A docking collar with male projections extending laterally therefrom is associated with one of the first and second barrel portions, and for each male projection, at least one complementary track is provided in a track-carrying member associated with the other of the first and second barrel portions. A biasing element, such as a gasket, facilitates securement of the first and second barrel portions when engaged with one another.
