Swipe will not generate any ammo during Mad Moxxi's arena missions; only money and the occasional health drop.

It is usually sufficient to put a single point in the Swipe skill, and equip a Scavenger or Survivor mod with a +3 bonus to Swipe when in particularly dire need of resupply.
The skill works very well in conjunction with Bird of Prey, as the number of loot drops is multiplied by the number of targets that Bloodwing hits.
Swipe does not require a kill, only for Bloodwing to successfully hit an enemy, whereupon the effect will trigger and items will pop out of the enemy.
The type of loot items (cash, Insta-Health Kits or ammo) generated appear to be similar to the algorithm that selects what type of loot items killed enemies will drop, and tends to be what your character happens to need at that moment (though not always).
