The heart of this pistol is a 5.5-inch 4150 CMV steel barrel threaded 1/2-28 for easy suppressor or muzzle device installation. Straight blowback operation keeps the system simple and reliable while the free-float aluminum M-LOK handguard provides ample real estate for lights, lasers, or fore-grips.
Spike’s Tactical machines both upper and lower receivers from billet 7075-T6 aluminum, then finishes them with a hard-coat anodized matte black surface. Omitting the forward assist, dust cover, and shell deflector trims weight without compromising durability.
The dedicated Glock-magazine lower features an integrated last-round bolt hold-open to speed reloads and an enlarged magazine release button for confident manipulation. Ambidextrous pictogram selector markings deliver both functionality and the distinct Spike’s aesthetic.
An adjustable polymer stabilizing brace and A2-pattern pistol grip round out the controls, allowing shooters to tailor length of pull and maintain familiar ergonomics. The upper includes a full-length Picatinny rail for optics; no sights are installed, keeping the platform ready for your preferred setup.
With its compact dimensions, quality components, and Glock magazine compatibility, this ST9G Gen II brings versatile 9 mm firepower to any collection.
