Description
The Great Lakes Striker 9mm Blue Titanium pairs a slate-blue Cerakote polymer frame with a ported, optic-ready black slide. It is a compact, 15+1 striker-fired pistol from Great Lakes Firearms and Ammunition of Sparta, Michigan, built for shooters who want a red dot and some color without paying custom-shop prices.
Great Lakes Striker 9mm Blue Titanium Overview
Great Lakes catalogs this model as the GL19BLU. Some distributor listings call the frame plain titanium, but photos and the color code show a muted blue-gray tone that reads closer to steel blue than to bright anodized blue. Underneath the color it is the same 4 inch, 15 round Striker as the rest of the line: steel slide with window cuts and ports, polymer frame with an accessory rail, and an RMR footprint milled into the slide.
That combination makes it a sensible platform for range sessions, red dot practice and general home defense, while the finish keeps it from looking like every other black compact in the safe.
The Blue Titanium Finish
Cerakote is a ceramic-polymer coating that resists scratches, solvents and corrosion better than paint. On this frame it is applied in a blue-gray shade that changes with the light: almost charcoal indoors, more clearly blue in daylight. The slide stays black, which keeps glare down at the top of the gun where your eye and the dot live. Expect small shade differences from the photos due to lighting and screens.
Slide, Porting and Optic Cut
The black Cerakote steel slide carries front and rear cocking serrations, lightening windows and ports cut over the barrel. Porting vents some gas upward at the muzzle, which helps the sights settle between shots. The trade-off is real: expect more muzzle flash, a sharper report at an indoor range, and carbon on the slide and any optic lens after a long session. The slide is milled for Trijicon RMR pattern optics, so a Holosun 507C or similar dot mounts without an adapter plate.
The fixed sights are basic and may not co-witness through every dot, so test your setup before relying on it.
Grip Texture, Rail and Trigger
Grip texture on the polymer frame is aggressive enough for wet or sweaty hands without chewing up skin on a short range day. A dust-cover rail accepts weapon lights, and the magazine release can be swapped for left-hand use. The flat-faced aluminum trigger breaks around 5.5 pounds according to retailer specs, with the usual striker-fired take-up before a defined wall. There is no thumb safety, so carry it only in a holster that fully covers the trigger guard. Gen3 pattern parts compatibility is claimed, but check each part individually.
Real-World Trade-Offs
Buying a Great Lakes pistol means trading brand history for features and finish at a modest price. Aftermarket support is thinner than for the biggest names, and resale value is lower. Check holster fit carefully with the ported slide and any optic. The maker lists 30 ounces, while one retailer quotes far less, so trust the maker figure. Cerakote holds up well, yet edges and the grip can show wear with daily holster use. Run a solid break-in before relying on it for defense.
Where It Fits Best
This pistol makes the most sense as a range and training gun that can double for home defense once you have proven it with your chosen load. Add a compact dot, a weapon light on the rail, and a quality holster, and you have a capable setup for a modest total cost. Shooters who carry daily should weigh the porting flash and the limited holster support before choosing it for concealment.
State Laws and Ownership
Colored frames do not change how a pistol is regulated. The pistol ships with two 15 round magazines. That capacity is illegal to sell or possess in some states and localities, including California, New Jersey, New York, Massachusetts, Washington and Illinois, and some states also restrict new handgun models through a roster or require a permit to purchase. Pennsylvania has no magazine capacity limit or roster, but a handgun purchase still goes through a background check at the dealer. Confirm your own state and local rules before ordering.
