H2S Hybrid 2 Stage NiB - Drop in Trigger|


Developed with pistol caliber carbine and defensive shooters in mind. The Stern Defense Hybrid 2 Stage trigger bridges the gap between Mil-Spec style trigger groups and high speed low drag competition triggers. The Stern Defense two stage trigger is a direct drop in replacement for your existing trigger and has endured a 250,000+ round torture test without failure. It features a smooth 2 lb first stage, leading into the positive 4 lb second stage that ends with a crisp break and predictable reset.  With our duty spring in place, long gone are the days of inadvertent bump fires and failure to reset concerns so common in the PCC market when using a drop in trigger.   Using our trigger on a rifle caliber? Want to step down the poundage?  Follow the included instructions to easily swap to our 3 pound green spring for the most solid wall and light break you have ever felt on a two stage trigger.



  •  Standard mil-spec pin size
  •  Use for AR15 and AR10
  •  6061 billet housing
  •  Trigger and disconnect machined from A2 tool steel bar stock.
  •  Hammer machined from  S7 shock resistant steel bar stock.
  •  Semi flat trigger bow
  •  Disconnect, Hammer and Trigger NiB Coated.



Stern Defense does not recommend the use of our green spring or other light poundage short reset triggers on pistol caliber carbines due to the reciprocating mass.  Please use our factory preinstalled spring on the H2S for use with pistol caliber carbines.

    These are outstanding triggers

    Posted by MattD on May 27th 2024

    I’ve tried other two stage triggers; Geissele, Timney, Triggertech, POF-USA, but I keep coming back to this one, because it literally beats all the others hands down. Smoothest, crispest wall and break by far. I have them in .40 S&W and .45 ACP PCCs, and my shot control and accuracy is the best I’ve ever achieved. They also look pretty good installed with Stern’s NiB BCGs, which I use in all my PCCs. I’m now going to put them into my .556 and 6.5 Grendel ARs. Highly recommended, especially on sale at a terrific value!

    Perfect trigger for the 9mm PCC build

    Posted by Jeff Bogardus on Aug 11th 2022

    I have almost 800 rounds through my 9mm PCC build and so far this trigger has been perfect for me. My comparisons are single stage Hiperfire and Geissle triggers, which I prefer in my AR15 builds. So this has been quite a pleasant surprise. Great transition and reset and while the claimed pull weights are accurate they seem a lot lighter than they actually are, Great trigger for my first drop-in, 2-stage...
