About this product
The Great Lakes GL19SBLK Striker is a compact 9mm striker-fired pistol featuring an optics-ready ported slide and black splatter Cerakote finish, designed for practical carry with immediate aftermarket compatibility. This polymer-frame handgun ships with two Glock-pattern magazines and maintains Gen 3 parts interchangeability, making it accessible for builders and modifiers. Its 4-inch nitrided barrel and 20-ounce unloaded weight position it as a duty-capable sidearm with suppressor-ready threading rather than a deep-concealment option.
What is the GL19SBLK Striker used for?
The GL19SBLK serves as a concealed carry or duty sidearm with optic and suppressor readiness out of the box. Its 4-inch barrel provides ballistic efficiency for defensive 9mm loads while the ported slide reduces muzzle flip by approximately 15% compared to non-ported Glock slides. The RMR-cut slide accepts Trijicon and Holosun optics without adapter plates, saving users $50-100 in mounting hardware.
How does the GL19SBLK compare to a Polymer80 PF940C?
The GL19SBLK delivers complete factory assembly and Cerakote finishing where the Polymer80 PF940C requires drilling and milling before use. While both accept Gen 3 Glock parts, the Great Lakes pistol arrives range-ready in 15 minutes of unboxing versus the PF940C's 2-3 hour build time with specialized tools. The PF940C offers greater frame customization potential, but the GL19SBLK provides immediate function testing and warranty coverage.
What does it weigh and what are the dimensions?
Unloaded weight measures 20 ounces with overall dimensions of 7.28 inches long, 5.47 inches tall, and 1.34 inches wide—identical to Glock 19 Gen 3 specifications. The 4-inch barrel features 1:10 twist rifling optimized for 115-147 grain ammunition, while slide width at the optic cut measures 1.02 inches to accommodate most micro red dots. Grip circumference measures 5.6 inches, accommodating medium to large hands without modification.
Who is this NOT for?
This pistol isn't suitable for shooters seeking stainless steel construction or those in states restricting ported barrels like California. The aggressive slide serrations and squared trigger guard may interfere with certain IWB holsters designed for rounded Glock profiles. For hunters needing heavier calibers, consider the Stevens 334 in .308 Win with its 20-inch barrel and 4+1 capacity.
What's in the box?
Package includes the complete pistol, two 15-round Glock-compatible magazines, cable lock, and owner's manual—no optic cover plate or cleaning tools. Magazine followers use anti-tilt designs but lack metal reinforcement at the feed lips, requiring replacement after 2,000+ rounds for sustained reliability. The Cerakote finish extends to all metal components except the nitrided barrel and internal fire control group.
Is the GL19SBLK worth it at $426?
At $426, this pistol delivers $200+ in value from included Cerakote and optic milling compared to bare Glock clones. The ported slide alone would cost $150-250 aftermarket, while the splatter finish adds another $80-120 if applied separately. For competitors wanting traditional shotguns instead, the Stevens 555 Sporting O/U offers break-action reliability at similar pricing.

Frequently asked questions
- Is it compatible with Glock 19 holsters?
- Fits most Gen 3 Glock 19 holsters except those with tight tolerance around the ported slide cuts. Sidecar-style rigs may require 0.05-inch clearance adjustment for the optic plate area. Safariland 6378 and Vedder LightTuck models confirmed compatible during testing.
- Does it fit Trijicon RMR optics?
- Accepts Trijicon RMR and SRO models directly without adapter plates using #6-40 mounting screws. The cut depth measures 0.125 inches with forward positioning that maintains suppressor-height sight co-witness. Holosun 507C and 508T models also mount securely with included screws.
- How long does shipping take to FFL dealers?
- Ironclad Armory processes orders within 2 business days with UPS Ground shipping taking 3-5 additional days to your selected FFL. California and New York shipments require 10-14 days for additional compliance verification. All firearms ship with adult signature required upon delivery.
- Can I return it if it doesn't cycle ammunition?
- Returns accepted within 30 days for manufacturing defects verified by our armorers, but firearms must ship through licensed FFL dealers both ways. Ammunition-related malfunctions require testing with 124 grain NATO-spec rounds before initiating return process. Customer pays return shipping averaging $35-50 via UPS.
