Glolck 9Mm Ammo Guide: Best Rounds

The Glock 9mm is one of the most popular handguns on the market, known for its reliability, accuracy, and versatility. When it comes to choosing the best 9mm ammo for your Glock, there are many factors to consider, including the type of shooting you'll be doing, the level of penetration you need, and the amount of expansion you require. In this comprehensive guide, we'll take a closer look at the best 9mm ammo rounds for your Glock, including their specifications, performance, and suitability for different applications.
Understanding 9mm Ammo

Before we dive into the best 9mm ammo rounds, it’s essential to understand the different types of 9mm ammo available.

Hollow point (HP) rounds, on the other hand, are designed to expand upon impact, creating a larger wound channel and reducing the risk of over-penetration. Jacketed hollow point (JHP) rounds combine the benefits of FMJ and HP rounds, offering a balance of penetration and expansion.
