Arex - Rex Zero - Rex Alpha - Dual Adjustable Flat Trigger - BLACK

Fits ALL Rex Zero DA/SA models: Full Size, Compact, Tactical, Alpha 

Will NOT work in any Sig Sauer Pistols!


* Please be sure to check out our Sig Sauer Trigger Reduced Power Sear Spring, which is also compatible with the Arex Zero.  This spring will decrease your trigger pull weight while keeping 100% ignition reliability.  On average, you can expect an instant trigger pull reduction by approximately  lb in Single Action in DA/SA pistols.


A direct replacement to your stock trigger for a smoother, more consistent pull.



We are offering this trigger also as a bundle with a lighter sear spring. It will result in decreasing the trigger pull weight in SINGLE ACTION by 1-1.25 lbs. Trigger pull weight in DA remains unchanged.


  • Reduces pretravel in DA
  • Reduces overtravel DA/SA 
  • Optimized *width*. Tighter & less ‘side-to-side’ wiggle vs. stock trigger
  • Optimized trigger pin and trigger bar holes - less wiggle
  • Shorter reset, more positive engagement
  • Straight trigger surface with grooves
  • This trigger alone reduces the perceived trigger pull weight. With stock curved trigger the pulling force is transferred through the middle of the trigger (apex of the curve). However, the flat design allows the shooter to position their finger lower on the trigger to take advantage of the increased leverage. Same principle as on our industry first SIG P-series flat adjustable trigger.
  • When used in combination with a lighter sear spring, 'actual' trigger pull weight is reduced as well


Promotes better trigger discipline - i.e. more accuracy. This is especially useful during rapid fire, which could happen in self-defense situations and competition.
