We report a search for production of long-lived charged massive particles in a data sample of 90 pb^{ -1} of \sqrt{ s} = 1.8 TeV p anti-p collisions recorded by the Collider Detector at Fermilab (CDF). The search uses the muon-like penetration and anomalously high ionization energy loss signature expected for such a particle to discriminate it from backgrounds. The data is found to agree with background expectations, and cross section limits of \cal{ O} (1) pb are derived using two reference models, a stable quark and a stable scalar lepton.
