Hi-Point Firearms, also known as Strassell's Machine, Inc (distributed by MKS Supply), is an American firearms manufacturer based in Mansfield, Ohio. All of their firearms are manufactured in several different locations in Ohio. Construction of products Pistols Hi-Point semi-automatic pistols are polymer framed handguns based on the blowback design. Different from other blowback design pistols such as the Walther PPK, the P-64, and the Astra 600 which use a heavy slide combined with a stiff recoil spring to hold the breech closed, these pistols use a heavier slide so they can use a softer recoil spring. When compared to breech-locking handguns of the same caliber and dimensions, the Hi-Point is rather top heavy. As with most blowback handguns, this pistol has fewer moving parts to clean and lubricate than its locked breech counterparts. While most semi-automatic pistols can be field stripped without the use of any tools, Hi-Point pistols require a small punch or a screwdriver and a hammer to remove a pin in the receiver, in order to permit slide removal (and thus enable field-stripping). Rather than being machined from forged steel, the slide is die cast from Zamak-3. Zamak is a zinc alloy which is often used in low cost firearms; previous manufacturers using this technique included Lorcin Engineering Company and Raven Arms. Die casting is particularly commonplace in Ohio, which influenced the decision to implement it. Uncommon for this construction, Hi-Point pistols are rated for +P ammunition in calibers up to .45 ACP. Blowback designs are generally simpler in design and easier and cheaper to manufacture than locked-breech recoil-operated firearms. While the fixed barrel of a blowback gun generally will contribute to improved accuracy, blowback guns usually need to be larger and heavier than a locked-breech gun firing the same caliber. Carbines The Hi-Point carbine is a series of pistol-caliber carbines manufactured by Hi-Point Firearms chambered for 9×19mm Parabellum, .40 S&W, 10mm Auto, .45 ACP and .380 ACP. They are very inexpensive, constructed using polymers and alloyed metals as much as possible, resulting in a reduction of production costs and sale price. It functions via a simple direct blowback action. Hi-Point carbines use a polymer stock, stamped sheet metal receiver cover, and a receiver and bolt cast from Zamak-3. The barrel is steel and button rifled using a 1-10" right hand twist. Use of zinc alloy Some people are wary of Hi-Points because of the use of
