Glock Flatback/Invincible Glock Switch – Semi/Full Auto M…

Product Overview

The Glock Flatback/Invincible Switch represents a significant evolution in aftermarket firearm components. Designed for the experienced Glock owner and enthusiast, this low-profile device enables select-fire functionality. Unlike earlier “always hot” designs locked in full-auto mode, this 2025 iteration features a crucial semi/full auto selector. This allows the user to toggle between firing modes discreetly. Its primary use is as a conversion device, integrating seamlessly with your existing platform to offer enhanced functionality for specialized applications. Crafted from durable polymer to match OEM specifications, it is engineered for those who demand both performance and discretion from their equipment.

Key Features

• Selectable Fire Control: The defining upgrade from previous generations, this switch allows the user to select between semi-automatic and full-automatic firing modes, providing versatility and control not found in earlier flatback designs.
• Concealed, Low-Profile Form Factor: Engineered to fit snugly against the back of the Glock slide, maintaining a minimal footprint. This design prioritizes discreet integration over obtrusive modification.
• Durable Polymer Frame: Constructed from high-strength polymer, ensuring a lightweight yet robust build that complements the material composition of the host firearm for reliable performance.
• Simplified Integration: Functions as an auto sear conversion device, designed for straightforward installation by a qualified gunsmith onto compatible Glock models to enable its select-fire capability.
• Dual-Action Capacity: The device facilitates a two-round burst function in its full-auto mode, offering controlled, short bursts rather than uncontrolled continuous fire.
• Modernized Design (2025): As a new release, this model incorporates the latest refinements in design and function based on user feedback and advancing component technology.

Performance & Applications

This component is designed for specific, controlled environments where its unique functionality can be properly utilized. It is not a general-purpose upgrade but serves niche roles.

For dedicated training facilities, the switch allows instructors and advanced users to safely train with and understand the characteristics of select-fire operation under strict supervision. The ability to switch back to semi-auto is crucial for drills that transition between firing disciplines.

In the realm of professional dynamic shooting sports held on authorized ranges, experienced competitors may employ this device in specialized divisions that allow for select-fire, using the two-round burst capability for engaging specific target arrays where split-second timing is a measured factor.

Finally, for serious collectors and firearms technology enthusiasts, this switch represents a functional piece of engineering innovation. It allows for the study and responsible use of firearm mechanics evolution, from a purely mechanical and historical interest perspective.
