One of the advantages of double-barreled shotgun with double triggers or SST, is that the second shot can be taken almost immediately after the first with merely a second trigger pull, without needing to manually operate the action (which will inevitably destabilize the gun from the shoulder position and affect aim), and can utilize different chokes for the two shots (assuming, of course, that full power shotshells are fired, at least for a double-barreled shotgun with an inertial type SST, as needed to toggle the inertial trigger). This can be noticeably faster than a pump shotgun, which requires manually pumping the fore-end to eject and reload for the second shot, and may be faster, or not slower, than a semi-automatic shotgun (as there are no bolt movements to delay the rechambering of a second shell). Note, however, in neither the pump or semi-automatic will the second shot be a different choke pattern from the first shot, whereas for a double, the two shots are usually with different chokes. Thus, depending on the nature of the hunt, the appropriate choke for the shot is always at hand. For example, while field hunting flushing birds, the first shot is usually closer than the second because the bird flies away from the shooter; so, the more open choke (and barrel) would be better for the first shot, and if a second shot is needed, as the bird is flying away, the more closed (and thus longer distance of an effective shot pattern) choke (and barrel) is then appropriate. Conversely, on a driven hunt, where the birds are driven towards the shooter, the closed (longer effective distance) choke (and barrel) should be fired first, saving the open (closer effective distance) choke (and barrel) for the now-closer incoming bird. None of this is possible with single-barrel shotguns, only with a double, whether S×S or O/U.
