Neither outlaws nor lawmen believed it possible to survive on the frontier without a horse and a handgun or shoulder weapon, preferably both. Some pistoleers required two guns in opposite holsters, loose and ready for quick double draws. Without horses, lawmen could not pursue outlaws fleeing from the towns, nor could outlaws escape from the towns. Except for a few gunmen, like the Daltons and the Earp brothers and their associates, tracking outlaws or escaping from the law on horseback was something a man did alone. Unless he needed help to stop and rob a train, even the convivial Jesse James often chose to ride alone.
