The only sort I can think are the smaller sort of missal a priest might use to offer daily Mass. The
modern TLM travel-size missals are far more compact than an altar missal, but are hardly small enough to be hand missals. I would suggest looking on Ebay or whichever, and with a bit of looking and patience, a full
Missale Romanum no larger than say, a 1945
St Andrew's Missal, can be found. The only disadvantage is the only ones I ever found were fairly old, so might lack most or all of the Feasts or Commemorations added in the twentieth century, 1846 and 1873 are the dates of priestly missals which could genuinely be classed as hand missals. I hope that answer is of some help.
