Introduction
Every so often, a product emerges that captures attention with its innovation and capabilities—something that seems almost too good to be true. The FSSG Fire Selector System is one such product, standing out as an exceptional aftermarket enhancement for Glock pistols. While it promises groundbreaking functionality, it remains a highly restricted item, available only to law enforcement and military personnel. In this article, we’ll explore the features, advantages, and implications of the FSS system, as well as compare it to another notable modification: the Invincible Glock Switch.
What is the FSSG Fire Selector System?
The FSSG Fire Selector System is an aftermarket device designed to transform Glock handguns into fully automatic select-fire weapons. Constructed from reinforced glass-filled polymer, this innovative attachment replaces the standard backplate on any Glock model. It’s marketed primarily by Jerry Peterson’s SCARS company, targeting military and law enforcement clients both in the U.S. and internationally.
Key Features of the FSSG
- Durability and Reliability
- Designed to be as durable as the Glock itself, the FSS is engineered to withstand the rigors of tactical use without compromising reliability.
- Easy Installation
- The FSSG can be quickly swapped with the original Glock backplate, ensuring that users can transition seamlessly between standard and select-fire modes.
- Universal Fit
- One of the standout features of the FSS is its compatibility with all Glock models, regardless of caliber. This universal fit enhances its logistical value for military and law enforcement units.
The Practical Advantages of the FSSG
Logistical Flexibility
The FSSG offers significant logistical advantages in operational settings. When a Glock pistol becomes inoperable, the FSSG can be swiftly removed from the malfunctioning weapon and attached to another fully functional Glock. This contrasts sharply with traditional full-auto models, such as the Glock 18, which require factory repairs or replacements, often leading to extended downtime.
Enhanced Tactical Options
The standard Glock 18 is limited to a single caliber—9mm—paired with a specific model size. This limitation can be a drawback in tactical situations where different calibers might be more effective. The FSSG allows operators to convert various Glock models, such as the Glock 19 or Glock 21, into full-auto configurations, expanding the versatility of their arsenal.
Overview of the Invincible Glock Switch
The Invincible Glock Switch is another aftermarket modification designed to convert Glocks into fully automatic firearms. Its features include:
- Compact Design: The Invincible Glock Switch is smaller and more discreet than many alternatives, making it easier to conceal.
- Quick Activation: The switch is designed for rapid engagement, allowing for quick transitions from semi-automatic to fully automatic fire.
- Material Quality: Typically made from high-strength materials, it promises durability similar to the FSS.
