It is semi-automatic, with a capacity of 6+1 12-gauge shells it is reloaded by breaking open the receiver and loading shells directly into the magazine tube, in a manner possibly inspired by the Cosmi Lusso, albeit with a traditional underbarrel magazine tube instead of one in the stock. The second weapon Alyx can acquire, the game's shotgun is a fictitious design vaguely reminiscent of the Techno Arms MAG-7, with an AK-esque receiver and a Franchi SPAS-12-esque barrel, magazine tube, and set of iron sights. Realizing that this section's overstayed its welcome a bit, Alyx decides to merge a few different observations into one screencap aside from showing what the end of the laser beam looks like, this also shows off two of the other ways the game alerts the player that the LDA is empty (in addition to the ammo counter on the grip, the slide locking back, and a small tone that sounds when it does so): the pistol's magazines all have bright orange followers (a feature of many real-life magazines, meant to make a locked-empty pistol more obviously distinct from a loaded or jammed one at a glance), and the bottom of the slide features a bright red LED that shines onto the user's hand when the it locks back (a feature real-world manufacturers have understandably been a bit hesitant to try). The reservoir also apparently has some means of manipulating the slide, since inserting a full mag with a partially-filled reservoir will lock the slide open to reload the reservoir, then drop it when the process is finished (not to mention its ability to forcibly release the slide with an empty magazine inserted) oddly, despite this, it refuses to release the slide when it's already locked open, leaving Alyx to do it herself. This is achieved through a couple of insect leg-esque arms (which the Combine seem awfully fond of) that reach into the ejection port and yank rounds out (a process which, going frame-by-frame, seems to take rounds from the magazine to the reservoir without them crossing the space between) when the magazine runs empty, it then manually places them straight into the ejection port to keep the gun fed. Midway through a gunfight in an abandoned subway station, Alyx shoves a new magazine into her fully-emptied LDA, and watches as the reservoir steals all of its ammo.
