45 GAP Ammo For Sale 


45 gap ammo for sale. When it comes to ammunition, there are numerous calibers to choose from. One such caliber that has recently gained popularity is the .45 GAP (Glock Automatic Pistol). Developed by Glock in collaboration with Speer, this cartridge offers a unique combination of power and compactness. 


This ammo was introduced in 2003 as an alternative to the larger .45 ACP (Automatic Colt Pistol) cartridge. The goal was to create a more compact round that could fit into a pistol grip with a smaller circumference, allowing for a more comfortable shooting experience. Glock, known for their innovative designs, partnered with ammunition manufacturer Speer to develop this new caliber.

Specifications of .45 GAP Ammo

The .45 GAP ammo is a rimless, straight-walled cartridge that measures 0.755 inches in length. It has a bullet diameter of .451 inches and operates at a maximum average pressure of 23,000 pounds per square inch (psi). The standard bullet weight for this caliber is 185 grains, although other bullet weights ranging from 165 grains to 230 grains are also available.


In terms of performance, the .45 GAP offers similar ballistics to the .45 ACP but in a more compact package. It delivers a powerful punch with a muzzle velocity ranging from 950 to 1,050 feet per second (fps). The muzzle energy of this ammo typically falls between 400 and 500 foot pounds (ft-lbs), providing excellent stopping power.

The recoil of the .45 GAP is often described as snappy but manageable. Due to its higher pressure, it generates more recoil compared to this ammo. However, this can be mitigated using a well-designed firearm with proper grip and recoil management techniques.

Advantages of .45 GAP Ammo

One of the primary advantages of this ammo is its compactness. The cartridge’s shorter length allows for a more ergonomic grip on the pistol, making it easier for individuals with smaller hands to handle. The reduced grip circumference can also improve control and accuracy during rapid fire.

Another advantage of the .45 GAP is its performance. This caliber’s higher pressure and velocity result in excellent terminal ballistics, making it a practical choice for self-defense. The larger bullet diameter also contributes to its stopping power, creating a more significant wound channel upon impact.

Furthermore, the .45 GAP offers compatibility with firearms chambered in .45 ACP through conversion barrels. This versatility allows shooters to switch between calibers without purchasing a new gun.

Disadvantages of .45 GAP Ammo

Despite its advantages, the .45 GAP does have a few drawbacks. One of the main concerns is the availability and cost of ammunition. While the popularity of this caliber has increased over the years, it is still not as widely available as more established calibers like 9mm or .45 ACP. As a result, purchasing this ammo may be more challenging and expensive compared to other options.

Additionally, the limited selection of bullet weights and types for this ammunition may restrict customization options for shooters who prefer specific loads for different purposes, such as target shooting or personal defense.


This ammo offers a compelling combination of power and compactness. Developed as an alternative to the larger .45 ACP, this caliber has found its niche among shooters prioritizing stopping power and ease of handling. With its excellent terminal ballistics and compatibility with .45 ACP firearms, this ammo is a viable choice for self-defense and other shooting applications. However, the limited availability and higher cost of ammunition may pose challenges for some shooters. Ultimately, the decision to adopt this ammunition as your caliber of choice should be based on your specific needs and preferences. 45 gap ammo for sale
