Choose either crossbows or guns. You can reload such weapons quickly.

<php>echo “<b>Prerequisites:</b>”;</php> Proficient with at least one gun (if you select guns) or crossbow (if you select crossbows)
<php>echo “<b>Benefit:</b>”;</php> The time required for you to reload your chosen type of weapon is reduced to a free action (for a hand, light, or repeating crossbow) or a move action (for a heavy crossbow, bluntbuster, double bluntbuster, long rifle, or dragon gun). Reloading a crossbow or gun still provokes an attack of opportunity.
<php>echo “<b>Normal:</b>”;</php> A character without this feat needs a move action to reload a hand, light, or repeating crossbow, or a full-round action to reload a heavy crossbow, bluntbuster, double bluntbuster, long rifle, or dragon gun.
