The AREX Delta is a true double action striker-fired pistol. As opposed to some hammerless pistols with fully cocked strikers, the Delta’s striker spring is only partially compressed as a cartridge is chambered. They have found the Striker Double Action system to be inherently safer than a single-action fully cocked striker. The AREX Delta gen.2 is available in three basic variants but each may be ordered in factory Optics Ready configuration enabling you to further enhance the pistol with a reflex optical sight. The most compact - M variant is practically identical in size to the first generation AREX Delta and reverse grip frame compatibility has been maintained for your convenience.  Modular design enables you to customize the firearm to your needs and preferences. Removable front and rear frame inserts incorporate slide guides and hold the complete fire control mechanism yet only the front insert is a serialized part that must remain with the firearm while everything else may be customized or exchanged if necessary or desired.  They have replaced the checkered grip texture of the first gen Delta with non-slip stippling as a direct result of your input. In addition to the original stippled indexing surfaces, the new gen.2 grip frames sport sandpaper-like stippled texture on all four sides of the grip with smooth edges to prevent garment snagging.
