Short of an ammunition problem such as a squib load…the two most likely revolver failures will be either short-stroking the trigger and temporarily locking it up until you release the trigger fully…or getting a round caught under the extractor star while loading or unloading under stress.
Both are user induced…not the fault of the revolver. Training and practice can reduce the chances of that occurring.
