Johnny Glocks Featured in Recoil Magazine September/October 2025 Issue #80 “Incoming” Section for New Umbra Trigger System

We’re honored to be featured in the Incoming section of the latest issue of Recoil Magazine, where the editors spotlight standout new products across the firearms industry. Coming in at #12, the Johnny Glocks Umbra Drop-In Trigger System for Shadow Systems pistols earned a mention as a precision upgrade designed specifically to overcome compatibility challenges with Shadow Systems’ proprietary internals.
Shadow Systems is known for producing high-performance, Glock-pattern pistols with unique components — including a proprietary firing pin that has created issues with many aftermarket Glock triggers. That’s where Johnny Glocks comes in.
A Purpose-Built Trigger for Shadow Systems Pistols
To solve these compatibility issues, we built the Umbra Trigger Kit from the ground up using OEM Shadow Systems parts, professionally reworked for that signature Johnny Glocks feel. The kit includes:
-
A flat-faced trigger shoe
-
A reduced-power firing pin safety spring
-
Three firing pin spring options (2.75 to 4.5 lbs) to customize your pull
-
An optional modified firing pin for even smoother operation
The result? A clean break, no over-travel, and a short, tactile reset — optimized specifically for MR920, XR920, and DR920P owners.
