Great Lakes GL19SRK Striker 9mm 4-inch 15rd Bull Shark

About this product

The Great Lakes GL19SRK Striker is a 9mm compact-framed, optics-ready pistol built on a polymer frame with a 4-inch ported barrel, a Glock-compatible magazine interface, and a proprietary Bull Shark Cerakote finish. This is a purpose-built, modern striker-fired platform designed for shooters who prioritize aftermarket compatibility and a robust defensive configuration. It bridges the gap between factory-standard compact pistols and full-blown custom builds.

What is the Great Lakes GL19SRK Striker used for?

The GL19SRK is primarily used as a duty-grade concealed carry pistol or a modular home defense platform. It directly supports a micro red dot optic and suppressor-height sights off the shelf, making it ready for a defensive nightstand or carry role within 5 minutes of opening the box. The 15-round standard capacity and 4-inch barrel provide a balance of firepower and shootability for intermediate-level training courses that demand reliability under high round counts, which its Gen3 Glock-style internal parts compatibility supports.

How does the Great Lakes GL19SRK Striker compare to a Polymer80 PF940C?

The GL19SRK is a more complete, ready-to-run package than the Polymer80 PF940C, which is a bare 80% frame requiring significant gunsmithing and parts sourcing. For a baseline comparison, the P80 requires procuring roughly $250 in OEM or aftermarket parts and a dedicated jig and tooling, totaling 3-5 hours of skilled labor before a first function check, whereas the GL19SRK ships ready to fire with a professionally applied proprietary finish and optic cut at the same $399 price point. The primary advantage of the P80 platform is the total absence of a serial number for those building under specific regulatory preconditions, while the GL19SRK's chief selling point is delivering a P80-like form factor in a fully assembled, warranty-backed configuration.

What does it weigh and what are the dimensions?

The pistol weighs 20 ounces (567 grams) unloaded and measures 7.28 inches in overall length, 5.04 inches in height (including magazine basepad), and 1.26 inches in width across the slide. The 4-inch barrel length positions it as a true compact; for reference, the Stevens 334 Rifle is often chosen for its comparable compactness in a different role, with a 20-inch barrel. These dimensions produce a firearm that carries well in an inside-the-waistband holster but maintains a serviceable grip for shooters with medium to large hands.

Who is this NOT for?

This pistol is not for first-time firearm owners or anyone seeking a simple, traditional double-action/single-action platform with an external safety. The lack of a manual safety lever and the short, 5.5-pound factory striker trigger weight require disciplined trigger finger management and holster selection. It is also not ideal for competitive shooters in USPSA's Carry Optics division, who would typically seek a 5-inch sight radius and full-size grip module like those found on custom Glock 34 variants.

What's in the box?

The package includes the completed GL19SRK pistol, one 15-round Glock-compatible polymer magazine, a polymer hard case with foam insert, a chamber flag, and the manufacturer's manual. Crucially, it ships with the optic plate cover installed but includes the necessary mounting screws for an RMR/SRO-pattern micro red dot—no separate purchase is required to mount an optic, unlike some base-model striker pistols that require buying their proprietary plates for up to $70 extra.

Is the Great Lakes GL19SRK Striker worth it at $399?

At a $399 price point, the GL19SRK is a compelling value for the shooter who wants an optic-ready, ported 9mm with a premium factory finish and broad parts compatibility without entering the $700+ custom shop market. Where a standard Glock 19 Gen5 MOS retails for around $600 before adding suppressor-height sights or an aggressive grip texture, this package delivers those features immediately. You are paying for a factory-built pistol that functions out of the box, not a parts kit project. For the shooter who wants a reliable, modern 9mm for home defense or everyday carry that can accept a red dot and a weapon light immediately, this is a strong starting platform, whereas someone wanting a classic sporting arm might look at a Stevens 555 Sporting O/U 12 Gauge.
