The Glock pistol, renowned for its simplicity and reliability, has also been a subject of ongoing modifications and aftermarket additions. One such modification that sparks considerable debate among Glock enthusiasts is the addition of a thumb safety, often referred to as the Cominolli safety. This guide will delve into the details of the Cominolli thumb safety, exploring its functionality, benefits, drawbacks, and overall impact on Glock pistol operation.
Understanding the Cominolli Thumb Safety
The Cominolli safety, named after its inventor, is a drop-in modification that adds a thumb safety lever to the Glock's slide. Unlike many aftermarket Glock modifications, the Cominolli safety doesn't require any irreversible changes to the pistol itself. This allows for relatively easy installation and removal, preserving the pistol's original configuration if desired. It's designed to function as a passive safety, meaning that the safety is engaged unless actively disengaged by the shooter.
How the Cominolli Safety Works
The Cominolli safety lever interacts with the Glock's firing mechanism. When engaged, it blocks the movement of the firing pin, preventing the pistol from firing, even if the trigger is pulled. Disengaging the safety is a simple action requiring a deliberate movement of the thumb. This adds an extra layer of security, particularly appreciated by those who prioritize safety features beyond the trigger itself.
Benefits of Adding a Cominolli Thumb Safety
- Enhanced Safety: The primary benefit is undoubtedly the increased safety. Adding a manual safety provides an extra barrier against accidental discharges, especially beneficial in potentially hazardous situations or for individuals with concerns about unintentional firing.
- Improved Grip: Some users find that the Cominolli safety also subtly improves their grip on the pistol, enhancing control and stability.
- Reversible Modification: The non-permanent nature of the Cominolli modification allows for easy removal, restoring the pistol to its original state if needed. This is a significant advantage over modifications requiring gunsmithing or altering original components.
- Relatively Easy Installation: While some mechanical aptitude is helpful, installing a Cominolli safety is generally considered easier than many other Glock modifications.
Drawbacks and Considerations
- Added Complexity: The addition of a safety, however simple, adds a step to the draw and firing process. This extra step can slightly increase draw time, potentially impacting reaction speed in self-defense situations. Extensive practice is crucial to mitigate this.
- Potential for Malfunction: Like any mechanical addition, there’s a potential, albeit small, for the Cominolli safety to malfunction. Regular cleaning and maintenance are essential to ensure its reliable operation.
- Cost: While not prohibitively expensive, the Cominolli safety is still an additional cost compared to using a standard, unmodified Glock.
- Aesthetics: Some users may find the addition of the safety lever aesthetically unappealing, preferring the clean, minimalist design of the standard Glock.
Is the Cominolli Safety Right for You?
The decision of whether or not to add a Cominolli safety to your Glock is highly personal. It depends on your individual priorities, shooting experience, and perceived risk tolerance. If you prioritize maximum safety above all else, and the potential impact on draw speed doesn't concern you, then the Cominolli safety might be a worthwhile investment. However, if you prefer the simplicity and speed of an unmodified Glock, it might not be the right modification for you. Thorough research and consideration are vital before implementing any modification to your firearm. Consider consulting with experienced shooters and firearms professionals before making a decision.
