TGS 2 Bearing Trigger System for For Maruzen APS Type 96
First PSS96 Zero Trigger - this looks the same as the Laylax zero trigger below - the branding is confusing
Laylax PSS96-Zero Trigger System for Type96
Ok, yes you are right! The last two trigger systems are exactly the same!
Here is a Diagram of Pros and Cons
King Arms Light Weight Trigger System

1) Has a light pull...it is easy to pull the trigger!

LayLax/First Factory Zero Trigger

Out of all of these triggers I would suggest the Zero Trigger. It is well worth the money. But you can also get its sister the King Arms Trigger...they are both suitable triggers...actually all of them are good triggers...I prefer a small, but strong build.
