BarrelBloks Enable Critical Car Holster Safety Testing: New Video Reveals Shocking Results
A new comprehensive safety test by respected holster manufacturer PHLster has exposed serious dangers with popular car holster products—and BarrelBloks played a crucial role in making this important testing possible.
Professional Safety Protocols Enable Real-World Testing
In this groundbreaking video, John from PHLster and automotive expert Net from @CollectorCarFeed conducted destructive testing on multiple Amazon car holsters using real firearms to ensure accurate weight and balance. To guarantee absolute safety during this high-risk testing, they used BarrelBloks in every firearm.

John, from PHLster, explains why they are using BarrelBloks
As John explains in the video: “We've disabled them all with a BarrelBlok so that a real round cannot be chambered and they're incapable of firing. And we have also used true weight inert dummy rounds that are also incapable of firing. So that this gun with a loaded magazine weighs exactly what it would weigh if you had loaded it with real ammo.”
This professional approach allowed them to conduct realistic testing while maintaining complete safety—even during extreme scenarios including airbag deployments and vehicle rollovers.
The Testing Results Were Shocking
The team put popular car holsters through four phases of increasingly demanding tests:
Phase 1 – Normal Driving Conditions: Most magnetic holsters failed immediately when driving over rough terrain equivalent to hitting large potholes.
Phase 2 – Seat Belt Pre-Tensioner Test: They demonstrated that proper on-body carry remains safe even during seat belt pre-tensioner deployment, contrary to common misconceptions.
Phase 3 – Airbag Deployment: Every single car holster either launched the firearm across the vehicle or was completely destroyed. One test gun was launched an estimated 150+ feet from the vehicle.
Phase 4 – Rollover Test: The few remaining holsters all failed during a gentle rollover simulation.
Critical Safety Issues Exposed

The testing revealed multiple serious safety concerns with these products:
- No safety warnings about airbag deployment zones
- Inadequate mounting systems using drywall screws on thin plastic panels
- Projectile risk – firearms become dangerous projectiles during crashes
- Compromised crash safety – hard objects placed in areas designed to be soft for occupant protection
- Reliability failure – firearms become inaccessible or inoperable when needed most
Why BarrelBloks Were Essential
This type of comprehensive testing would be impossible without proper safety equipment. BarrelBloks enabled the team to:
- Use real firearms for accurate weight distribution testing
- Conduct extreme testing scenarios including airbag deployments and rollovers
- Maintain absolute safety throughout hours of high-risk filming
- Focus on the test results without safety concerns
The testing involved launching firearms at high velocity, vehicle crashes, explosions, and rollover scenarios—exactly the kind of situations where BarrelBloks prove their value in maintaining safety while enabling important research.
Professional Recommendation: Avoid Vehicle Holsters

Both testers, with extensive experience in firearms and automotive safety, concluded that these popular car holster products pose unacceptable risks. Their professional recommendation aligns with most firearms safety experts: carry firearms on-body rather than using vehicle-mounted systems.
As they noted: “Whether or not you choose to use a car holster… is up to you. The question I would ask, does it have enough advantages to outweigh the cons here?”
Safety First, Always
This video demonstrates both the importance of proper safety testing and the value of professional safety equipment. BarrelBloks enabled critical safety research that could potentially save lives by exposing dangerous products and practices.
When conducting any firearms testing or training, proper safety equipment isn't optional—it's essential. BarrelBloks provide that essential safety margin that allows professionals to conduct important work while maintaining absolute safety.
