Look, I don't care one way or the other about tap-rack-bang orthodoxy spats, but the second strike requirement came about directly from the experiences of past warriors and what they wanted to see in a sidearm. You seem incapable of remembering that certain units in WW2, in both theaters, were cut off from resupply for extended periods. Other units in Korea and Vietnam were likewise using every damn round they had, perfect or not. There you are, running low on ammo as a unit. You have some suspect boxes of ammo that are showing badly that they were fished out from the surf zone. Despite what the modern doctrine might say to do about ammo with iffy primers, the Army wanted the ability for the sidearm to take more than one whack at a primer if its operator wanted it to. That's immaterial, the Army wanted that chance to be present no matter how remote. I didn't write the RFP, I am just explaining that second strike capability wasn't in there randomly. Again, that is irrelevant as to why the DoD added second strike capability to the XM9 RFP. IIRC, the ability to do so wasn't a JSSAP requirement for the aborted .45ACP trial.
