Hi-Point Firearms manufactures polymer-framed, semi-automatic pistols based on the blowback design. Unlike other pistols, which use a heavy slide and stiff recoil spring to hold the breech closed, Hi-Point pistols use a heavier slide and softer recoil spring. This design choice has led to some criticism of Hi-Point pistols for their weight and size. Notably, the slides of Hi-Point pistols are made of ZAMAK-3, a zinc-aluminum alloy that is popular in the die-cast industry. While ZAMAK-3 is not as strong as steel, it is still held to high industrial standards and is known for its high ductility, impact strength, and tensile strength.

What You'll Learn
Hi-Point slides are made of Zamak-3, a zinc-aluminium alloy
Hi-Point Firearms manufactures polymer-framed semi-automatic pistols based on the blowback design. Unlike other pistols, which use a heavy slide combined with a stiff recoil spring to hold the breech closed, Hi-Point pistols use a heavier slide so they can use a softer recoil spring. This design choice makes the pistol top-heavy when compared to breech-locking handguns of the same calibre and dimensions.
Hi-Point pistols are constructed using polymers and alloyed metals, which reduces production costs and sale prices. The slide is die-cast from Zamak-3, a zinc-aluminium alloy (ZnAl4) that is popular in the die-casting industry. Zamak-3 is 96% pure zinc, with a blend of 4% aluminium, magnesium, and copper, along with a pinch of iron, cadmium, and tin. It has a melting point of 718-728°F and can be easily coated and painted.
Zamak-3 is known for its high ductility, impact strength, and tensile strength of 40,000 lbs. It is also non-ferrous, meaning it will not attract a magnet. This alloy is commonly used in commercial items such as oxygen tank wrench keys, exterior door handles, gearshift handles, and seat belt components.
The heavy slide in Hi-Point pistols is a significant factor in the gun's low price point. The slide is essential in the pistol's direct blowback system, where the breech must remain closed until pressure levels have dropped to a safe level. A heavy slide helps retard the blowback action, slowing the action before the spring forces it back into battery.
While the heavy slide in Hi-Point pistols contributes to their weight and size, it also helps reduce recoil. The slide's weight and design ensure the pistol's reliability and durability, making it a popular choice for those seeking an affordable, functional firearm.

The slide is heavy to absorb the rearward force generated by the bullet
The slide of a pistol is an important component that affects its performance and handling. In the context of Hi-Point Firearms, the slides are notably heavier than those of other blowback design pistols. This weight serves a specific purpose in the pistol's operation and shooting experience.
Hi-Point semi-automatic pistols are polymer-framed handguns based on the blowback design. Unlike other pistols that use a heavy slide with a stiff recoil spring to keep the breech closed, Hi-Point pistols utilise an even heavier slide to accommodate a softer recoil spring. This design choice makes the pistol top-heavy when compared to breech-locking handguns of similar calibre and dimensions.
The weight of the slide plays a crucial role in absorbing the rearward force generated by the bullet during firing. A heavier slide provides a smoother recoil, reducing the flip or muzzle rise of the pistol. This is because a heavier slide cycles slower, which can help to mitigate the felt recoil. Conversely, a lighter slide results in sharper recoil and increased muzzle flip due to the faster cycling speed.
Additionally, the weight of the slide impacts the pistol's balance, affecting the shooter's ability to aim and transition between targets. A heavier slide places the pistol's overall balance under the trigger guard, allowing for faster aiming and target acquisition. This weight distribution also helps the sights return to the same spot after each recoil, contributing to the consistency of the shooting experience.
It is worth noting that while the heavier slide in Hi-Point pistols offers advantages in recoil management and balance, it also introduces trade-offs in terms of size and weight. The heavier slide contributes to the pistol's top-heavy nature, and the overall weight of the pistol may be a consideration for some users. However, the heavier slide allows for a softer recoil spring, which can make it easier to rack the slide and operate the firearm, especially for those with reduced hand strength.

The slide is heavy to save on cost and machining
Hi-Point Firearms manufactures polymer-framed handguns based on the blowback design. Unlike other pistols that use a heavy slide and a stiff recoil spring to hold the breech closed, Hi-Point pistols use a heavier slide so they can utilise a softer recoil spring. This makes the Hi-Point pistol top-heavy when compared to breech-locking handguns of the same calibre and dimensions.
The slide in a Hi-Point pistol is heavy because it is made of ZAMAK-3, a zinc-aluminium alloy. This alloy is popular in the die-casting industry and is known for its high ductility, impact strength, and tensile strength. The use of ZAMAK-3 allows Hi-Point to save on cost and machining while still delivering a reliable product.
The weight of the slide is also important for the pistol's functionality. In a blowback retardation system, when a round fires in a semi-automatic handgun, the slide cycles back, ejecting the spent cartridge case and inserting a new round from the magazine into the chamber. The weight of the slide is necessary to retard (slow) the action before the spring forces it back into battery. The heavier the cartridge, the heavier the slide needs to be.
The use of ZAMAK-3 also contributes to the indestructibility of the pistol's design. Hi-Point adds steel to the frame for extra strength and uses steel barrels and other components, but the bulk of the slide is ZAMAK-3. This material is not only strong but also easy to work with, as it can be electroplated, wet painted, and chromate conversion coated.
The weight of the slide is a trade-off, as it makes the pistol heavier overall but allows for a softer recoil spring and improved functionality. The weight is also a sign of reliability, as a heavier slide can better handle the recoil of cartridges.

The slide is oversized and makes the firearm heavy
Hi-Point Firearms manufactures polymer-framed semi-automatic pistols based on the blowback design. Unlike other pistols, which use a heavy slide combined with a stiff recoil spring to hold the breech closed, Hi-Point pistols use a heavier slide so they can utilise a softer recoil spring. This makes the slide oversized and the firearm heavy.
The slide's weight is a critical factor in blowback-operated pistols, as it helps slow the action before the spring forces the slide back into battery. The more stout the cartridge, the heavier the slide needs to be. For example, in a 9mm or 45ACP chambered locked-breech blowback pistol, a significantly heavy slide is required.
Hi-Point pistols use a direct blowback system, which necessitates a heavy slide to counteract the pressure generated by the 9mm cartridge. This design choice contributes to the overall weight of the firearm. Additionally, the slide's size and weight make it challenging to rack the firearm and fix malfunctions.
The slide is constructed from ZAMAK-3, a zinc-aluminium alloy (ZnAl4) that is commonly used in the die-casting industry. This alloy provides high ductility, impact strength, and tensile strength, making it suitable for the slide's function. However, the use of this alloy in the slide contributes to the overall weight of the firearm.
While the oversized slide adds weight to the firearm, it also has its advantages. The weight of the slide helps to reduce recoil, making the firearm more comfortable to shoot. Additionally, the ZAMAK-3 alloy used in the slide is known for its indestructibility, contributing to the firearm's durability. Despite the weight, the guns work, and for the price, they are hard to beat.

The slide lock is activated by pulling the locked slide further back
Hi-Point Firearms manufactures polymer-framed handguns based on the blowback design. They are constructed using polymers and alloyed metals, making them inexpensive. While the slide is not made of plastic, it is die-cast from Zamak-3, unlike other pistols which are machined from forged steel.
Now, onto slide locks. The slide lock is a crucial aspect of firearm safety, and it is important to understand how it works. The slide lock is activated by pulling the locked slide further back, and it is a two-part process. Firstly, the slide must be pulled all the way back. Secondly, the slide stop lever, also known as the slide release, needs to be pushed up. This lever is usually small and located on the left side of the firearm. When the slide is pulled back, the lever aligns with a notch in the slide, and pushing the lever up will lock the slide open.
Locking the slide back serves multiple purposes. It can make it easier to load a pistol with a difficult-to-manipulate slide. Additionally, locking the slide back is a good way to verify that the gun is unloaded and safe. It is also useful when conducting maintenance or clearing a stoppage.
It is worth noting that some semi-automatic pistols do not have a slide stop, so it is important to be familiar with the specific firearm you are handling. Additionally, some slides may not lock back due to modifications. In such cases, an empty chamber indicator may be necessary to ensure safety.
