We present a dynamical mechanism for completing inflationary phase transitions via bubble nucleation which can satisfy all known constraints for a wide spectrum of models and parameters. The approach is a generalization of the recent extended inflation model which corrects a serious flaw. We find an essentially model-independent bubble-size distribution which may be important for large-scale structure.
