Hi-Point Firearms
The Hi-Point HP15P 300 Blackout pistol brings modern tactical capability to the plate-carrier and truck-gun crowd without the typical price tag. Built on a forged aluminum upper and lower receiver with Picatinny rail mounting, this 10.5-inch threaded-barrel pistol hits harder than 5.56 in a compact package—ideal for hunting, range work, or dedicated short-range defense. The 300 Blackout cartridge shines in suppressed loads and subsonic ammunition, making this platform a genuine alternative to standard pistol-caliber options.
The HP15P ships with milspec internals where it matters: a mil-spec bolt release, charging handle, and manual safety keep the controls familiar to anyone versed in AR platforms. The 9.5-inch M-LOK handguard gives you real estate for lights, lasers, or slings without bloat, while the Blade-style polymer brace and A2 grip provide a solid, repeatable shooting platform. The A2 birdcage muzzle device comes standard; that 5/8x24 thread pitch on the barrel opens the door to suppressors, flash hiders, or muzzle brakes purpose-built for the cartridge.
Magazine capacity runs 30+1 with the included standard magazine, and the 1:7 barrel twist is optimized for the full range of 300 Blackout loads. At 4.25 pounds unloaded, it won't tire your arm during an extended range session. This is an uncomplicated, no-nonsense pistol that does one thing well—hit targets at close to intermediate distance with real power and minimal noise when run suppressed.
