For hunting and self-defense, 180-grain bonded-core rounds are a great choice. They offer excellent weight retention and controlled expansion, making them reliable in critical situations.

Using high-quality, factory-loaded ammunition is always a smart move. It helps ensure your gun functions properly and reduces the chance of malfunctions.
To keep recoil manageable, loads between 155 and 180 grains strike a good balance. They provide enough power while still being controllable, which can improve your shot placement.
Focusing on these ammo types will help your Glock 20 perform reliably in different scenarios. They also support maintaining precision and durability, whether you’re in the field or at the range.
Size, Weight, and Handling of the Glock 20
Choosing the right ammunition for your Glock 20 is only part of the equation; handling its size and weight effectively will influence your shooting experience.
As a full-size handgun, the Glock 20 measures 8.07 inches in length and weighs around 30.51 ounces when unloaded. That gives it a solid, stable feel, especially with its potent caliber.
Its 1.34-inch width helps you grip it firmly, giving you better control during recoil.
The ergonomic design includes a modular grip system with interchangeable backstraps, so you can customize the fit and comfort to match your hand.
With a height of 5.51 inches and a trigger distance close to 70 mm, you’ll find it easier to achieve a controlled, consistent trigger pull.
