Frequently Asked Questions

What are the key California-compliant features of the Shadow Systems XR920?

The California-compliant Shadow Systems XR920 includes a magazine disconnect, which prevents firing without a magazine inserted, and a loaded chamber indicator (LCI) that visually signals if a round is chambered. These features are mandated by California law for handgun sales.

How does the Shadow Systems XR920 compare to a Glock 45?

The XR920 is often compared to the Glock 45, featuring a slide length similar to a Glock 19 and a grip size akin to a Glock 17. It offers enhanced factory features like aggressive stippling, a flared magwell, and suppressor-height sights, providing more out-of-the-box customization than a standard Glock 45.

What accessories were installed on the Shadow Systems XR920 in the video?

In the video, a Streamlight TLR-7 HL-X weapon-mounted light and a Vortex Defender-ST enclosed solar micro red dot sight were installed on the Shadow Systems XR920. The installation process for both accessories was demonstrated.

Is the Shadow Systems XR920 compatible with Glock 19 holsters?

The XR920 may fit in some Glock 19 holsters, particularly those designed for models with weapon lights like the TLR-7 series. However, due to slight variations in dimensions and accessory fit, a snug fit is not guaranteed, and some holsters might require minor modifications or may not be compatible at all.
