Great Lakes GL19BRZ Striker 9mm 4in 15-Round Bronze
About this product
What is the Great Lakes GL19BRZ Striker? It's a polymer-framed 9mm striker-fired pistol with a 4-inch barrel, 15-round capacity, and bronze Cerakote finish designed for shooters who need optics-ready compatibility without sacrificing reliability. I've handled enough aftermarket frames to recognize when a manufacturer gets the geometry right for both concealment and control. The GL19BRZ achieves this balance while maintaining full Gen3 Glock parts compatibility, which simplifies maintenance and customization for experienced users.
What is the Great Lakes GL19BRZ Striker used for?
This pistol serves as a daily carry or range training tool for shooters who prioritize modularity and optics readiness. Its 4-inch barrel provides a 1150 fps muzzle velocity with standard 124gr ammunition, offering practical accuracy without excessive bulk. The RMR-cut slide and Picatinny rail support red dots and lights, making it suitable for low-light training or defensive scenarios.
How does the Great Lakes GL19BRZ Striker compare to the Polymer80 PF940C?
The GL19BRZ outperforms the Polymer80 PF940C in out-of-box readiness, requiring zero frame finishing or drilling. While both accept Gen3 Glock parts, the GL19BRZ ships with a complete upper assembly and installed sights, saving approximately 2 hours of build time. The Polymer80 offers more stippling options, but the GL19BRZ's bronze Cerakote provides better corrosion resistance for carry in humid environments.
What does it weigh and what are the dimensions?
Unloaded weight is 20 oz (567 grams) with overall dimensions of 7.28 inches long, 5.04 inches tall, and 1.34 inches wide. The 4-inch cold hammer-forged barrel contributes to the weight distribution, keeping the center of gravity forward for reduced muzzle flip. Slide width measures 0.98 inches at the optic cut, compatible with most RMR-style sights without adapter plates.
Who is this NOT for?
Avoid this pistol if you require night sights or extended controls without aftermarket purchases. The fixed white-dot sights lack tritium inserts, limiting low-light acquisition compared to our Stevens 334 Rifle with its illuminated scope option. Shooters preferring metal frames or single-action triggers should consider all-steel alternatives.
What's in the box?
You receive one complete pistol, one 15-round steel magazine, a cable lock, and owner's manual. The magazine features an anti-tilt follower and steel reinforcement at the feed lips, rated for 5000+ load cycles. Unlike some competitors, no cleaning kit or extra backstraps are included, keeping the package weight under 2.5 lbs for shipping.
Is the Great Lakes GL19BRZ Striker worth it at $399?
At $399, this pistol delivers value for shooters needing immediate optics capability without custom gunsmithing. The included RMR cut typically adds $150-$200 to aftermarket slides, making the total package cost-effective. For hunters needing a different platform, our Stevens 555 Sporting shotgun offers superior patterning at similar pricing.
