Johnny Glocks Featured in Recoil Concealment: New Umbra Trigger Kit for Shadow Systems Pistols

We’re excited to announce that Johnny Glocks has been featured in the latest issue of Recoil Concealment magazine in a standout article by Steven Kuo, titled “Piercing the Iron Curtain.” The article spotlights Shadow Systems’ new California-compliant pistols and gives a big shoutout to the newly developed Johnny Glocks Umbra Trigger Kit — purpose-built for the MR920, XR920, and DR920P platforms.

Whether you're running a compensated DR920P, or tuning a California-compliant MR920 or XR920, this new trigger is designed to deliver exactly what you’ve come to expect from a Johnny Glocks trigger: precision, control, and clean, consistent breaks.

Shadow Systems Pistols – Now California-Compliant

The article is a must-read for anyone interested in how top-tier handgun manufacturers are navigating California’s restrictive handgun roster. The MR920, XR920, and DR920P all include required compliance features like a loaded chamber indicator and magazine disconnect, yet still offer high-end ergonomics, slide cuts, optic mounting systems, and fluted barrels.

Why Johnny Glocks Built a Dedicated Trigger Kit

As Recoil Concealment reveals, Johnny Glocks worked directly with Shadow Systems OEM components to build a complete aftermarket Glock trigger system that works seamlessly with their proprietary internals — including their round firing pin. This new kit is called the Umbra Trigger Kit, and it’s available now at johnnyglocks.com.

You’ll get:

• The flat-faced Vex Deux trigger shoe
• A longer safety dingus with improved geometry
• A reduced power trigger return spring
• A reduced power firing pin safety spring
• Three firing pin springs (4, 4.5, and 5 lb) to tune your preferred pull weight
• Optional modified firing pin for even greater refinement

Recoil Concealment tested it in both the MR920 and DR920P, reporting a smooth 4-pound break in one setup and a 3-pound match-ready trigger in another. Clean, crisp, minimal overtravel, and short reset — exactly what you expect from Johnny Glocks.

Excerpt:

The new Johnny Glocks Umbra trigger kit is a complete replacement and will be in their Combat style, with no separate Competition kit. The flatfaced Vex Deux trigger shoe is new, featuring a longer safety dingus with improved fulcrum point and a reduced power spring. There’s also a reduced power firing pin safety spring and three firing pin springs (4, 4.5, and 5 pounds) to dial in your desired feel. All the components are OEM from Shadow Systems and worked over by Johnny to deliver the trigger pull you’ve grown to expect from him. The modified firing pin is an optional upgrade. We installed the complete kit in the MR920, swapping out the firing pin spring to achieve a 4-pound trigger pull. It’s super clean and smooth, with a crisp break, no overtravel, and a short reset.
