Standard Manufacturing showed DP-12, a shotgun that can shoot two rounds with one racking. This year they showed off the Volleyfire, a pistol that can shoot two rounds at the same time with one trigger pull.
It is chambered in .25acp for now, but they are seriously considering other calibers as well. It looks very similar to concepts used by COP .357 and Derringers as well.
They also came out with 1911s. The quality was definitely present.
