Let’s Talk About Stern Defense H2S Hybrid 2 Stage Drop In Trigger
The Stern Defense H2S Hybrid 2 Stage Drop In Trigger promises to bridge the gap between a standard mil-spec trigger and a high-performance competition trigger, particularly for PCCs and defensive rifles. Marketed as a direct drop-in replacement with enhanced reliability and a crisp trigger pull, it piqued my interest as I’ve been searching for a trigger upgrade for my AR-9 pistol caliber carbine. With a 2 lb first stage and a 4 lb second stage using the factory spring, this trigger aims to improve accuracy and control, addressing common issues like bump-firing with PCCs.
I’ve always tinkered with my firearms, striving for enhanced performance and reliability. The promise of a smoother, more consistent trigger pull in my PCC, which sees a lot of range time, was particularly appealing. The Stern Defense H2S Hybrid 2 Stage Drop In Trigger seemed to offer a balance of performance and dependability.
The trigger arrived in a no-frills package. My initial impression was positive, noting the solid feel of the 6061 billet housing and the clean machining of the A2 tool steel trigger and disconnect. The semi-flat trigger bow felt comfortable to the touch.
I considered triggers from Geissele and CMC Triggers before deciding on the Stern Defense H2S Hybrid 2 Stage Drop In Trigger. Ultimately, I chose the Stern Defense offering due to its competitive price point and design specifically tailored for PCC applications. The value proposition seemed compelling.
I was cautiously optimistic. The build quality appeared solid, but the true test would be its performance in the field, specifically the trigger pull and reset under rapid fire conditions. It remained to be seen if it could live up to its claims.
Real-World Testing: Putting Stern Defense H2S Hybrid 2 Stage Drop In Trigger to the Test
First Use Experience
I installed the Stern Defense H2S Hybrid 2 Stage Drop In Trigger in my Foxtrot Mike 9mm PCC and headed to the local indoor range. The initial session consisted of running various drills, including rapid-fire strings and controlled pairs, at distances ranging from 7 to 25 yards. The range was well-lit and climate-controlled.
The trigger performed admirably. The two-stage action was immediately noticeable, with a smooth take-up followed by a crisp, clean break. The reset was positive and predictable. I experienced no issues with light strikes or failures to reset during the first range session.
The installation was straightforward, and no adjustments were needed initially. I did note that the pins included with the trigger were slightly tighter than the factory pins. This required a bit more force to install.
Extended Use & Reliability
After several months of use and approximately 1000 rounds of mixed 9mm ammunition, the Stern Defense H2S Hybrid 2 Stage Drop In Trigger continues to perform reliably. I’ve run it in various conditions, including a few outdoor range days with moderate wind and dust. The trigger remains consistent.
There are no visible signs of wear and tear on the trigger components. I have followed Stern Defense’s recommendation and used the factory-installed spring for PCC use, resisting the urge to swap to the lighter spring. Cleaning is simple.
The Stern Defense H2S Hybrid 2 Stage Drop In Trigger outperforms the stock trigger. It offers a significant improvement in trigger control and accuracy, especially during rapid-fire scenarios. The predictability of the trigger break has become a real asset.
