All about the trigger.
One Company Found a Way To Make a Glock Gun Even Better
ZEV Technologies is known for its upgrades for Glock pistols. ZEV triggers are used regularly in competition Glocks, and their magwells and baseplates see use as well. But in early 2019, ZEV moved from just producing accessories to producing their own take on the Glock design: The ZEV OZ9.
How does the OZ9 improve on the Glock? Is it a practical pistol for the average user?
The primary change between the OZ9 and the Glock is that the OZ9 moves the fire control group into a metal “frame” similar to that found on the SIG P320. The frame fits into the plastic grip, which allows the grip to be easily swapped for one that the user prefers. The internal frame itself also has some slight improvements on the original Glock design, featuring slightly longer slide rails for increased theoretical accuracy.
However, apart from that, the frame is almost completely the same as a regular Glock. The position of the trigger bar, extractor, and frame rails are almost identical to a regular Glock, as an overlay shows. The ZEV OZ9’s slide also features a striker safety of the same style as that of a regular Glock.
The adherence to the Glock layout makes sense for ZEV as they are used to optimizing parts and building a pistol around it. Switching to the steel frame layout and extending the slide rails are the simplest upgrades they could make while keeping the pistol largely mechanically the same.
