Glock 48 vs 19: Comparing Concealability and Performance

When choosing a handgun, particularly for concealed carry, enthusiasts and professionals often compare the Glock 19 and Glock 48 models. The Glock 19 has been a standby in the firearms industry for its reliability and versatile use as a service and concealed carry weapon. It boasts a double-stack magazine that increases capacity, making it a preferred choice for many who prioritize ammunition availability.

The Glock 48, on the other hand, is a newer entrant that offers a slimmer profile due to its single-stack magazine. This feature, along with its slightly longer barrel than the Glock 19, has made it an appealing option for those seeking better concealment without sacrificing barrel length. While the Glock 48 may have a lower capacity than the Glock 19, it tends to be easier to conceal, making it an exciting option for users with a strong preference for stealth and comfort.

Key Takeaways

  • The Glock 19 is versatile for service use and concealed carry, with a higher capacity for ammunition.
  • The Glock 48 features a slimmer profile for easier concealment while maintaining a comparable barrel length.
  • Both models are significant in the context of firearms industry design preferences, performance, and personal carry considerations.

Design and Ergonomics

When comparing the Glock 48 and Glock 19, design and ergonomics encompass vital differences in size, weight, and the user's interaction with each firearm. This section addresses these aspects by breaking down both models' dimensions, frame, and sighting options.

Dimensions and Weight

Glock 48:

  • Overall Length: 7.28 inches
  • Width: 1.1 inches
  • Height: 5.04 inches
  • Weight (unloaded): 20.74 ounces

Glock 19:

  • Overall Length: 7.36 inches
  • Width: 1.26 inches
  • Height: 5.04 inches
  • Weight (unloaded): 23.63 ounces

While both pistols are roughly the same length and height, the Glock 19 is wider and heavier due to its double-stack magazine, which also adds to the overall weight when loaded.

Frame and Comfort

The frames of Glock 48 and Glock 19 play a significant role in how comfortable they are to handle.

  • Glock 48: Known for its slimmer profile, it is favored by those seeking a more concealable option with a single-stack magazine, making it lighter and potentially more comfortable for various hand sizes.
  • Glock 19: This model has a wider grip to accommodate its larger capacity magazine, which, while bulkier, provides a solid and balanced feel in hand. Front serrations on newer generations enhance the grip during manipulation.

Both guns feature the classic Glock polymer construction and functional, if somewhat blocky, ergonomics, with designs that fit well into the vast majority of hand sizes.

Sights and Accessory Rail

The sighting options on both the Glock 48 and Glock 19 cater to different preferences:

  • Glock 48: Typically comes with factory polymer sights, which are durable and functional. There's room for customization with aftermarket sights, like the AmeriGlo sights, for those who prefer a more premium sighting option.
  • Glock 19: This gun provides more versatility as it comes with factory polymer sights and multiple sight options, including the famous AmeriGlo sights, often preferred for their visibility.

The Glock 19 includes a built-in accessory rail that allows for the attachment of tactical accessories such as lights and lasers, which the Glock 48 lacks due to its slim design. This can be a consideration for those looking to utilize their pistol in a broader range of scenarios requiring such additions.

Performance and Specifications

When comparing the Glock 19 and Glock 48, one will notice differences in caliber, ammo capacity, barrel length, and trigger system that directly affect their performance. Each firearm has distinct specifications that cater to varied preferences and purposes.

Caliber and Ammo Capacity

The Glock 19 and Glock 48 chamber the 9x19mm cartridge, renowned for its balance of recoil and stopping power. Where they diverge is in ammo capacity:

  • Glock 19: Standard magazine holds 15 rounds.
  • Glock 48: Slimline magazine accommodates ten rounds.

The increased ammo capacity of the Glock 19 reflects its design as a more versatile firearm suitable for situations where a higher round count is preferable.

Barrel Length and Trigger System

The barrel length of a firearm is a crucial factor in its accuracy and ballistic performance.

  • Glock 19: Boasts a 4.02-inch barrel.
  • Glock 48: Features a slightly longer 4.17-inch barrel.

As for the trigger system, both models employ Glock's Safe Action system, which includes a consistent trigger pull and three automatic independently-operating safety mechanisms. The trigger distance is approximately 2.80 inches, and the standard trigger pull is roughly 5.8 lbs.

Accuracy and Recoil

Accuracy and recoil are influenced by various factors, including barrel length and the firearm’s weight.

  • Glock 19: Given its shorter barrel and slightly heavier weight when loaded, the Glock 19 remains a highly accurate choice with manageable recoil. It's often considered well-suited for both self-defense and law enforcement applications.

  • Glock 48: Its longer barrel and lighter weight can increase accuracy, which might be felt when engaging targets at increased distances. The reduced weight may, however, result in a perception of increased recoil.

Each model's performance will be influenced by the individual shooter’s experience, preference, and situational needs.

Concealment and Carry Options

When comparing the Glock 48 and Glock 19, one must consider the differences in magazine capacity and the implications for concealed carry and comfort.

Magazine Types and Capacity

The Glock 19 utilizes a double-stack magazine, offering a standard capacity of 15 rounds. This configuration contributes to the pistol's wider grip, which some may find less comfortable for concealed carry. In contrast, the Glock 48 comes equipped with a single-stack magazine holding ten rounds. This reduces the firearm's width, making it more concealable.

  • Glock 19: Double-stack, 15 rounds
  • Glock 48: Single-stack, ten rounds

Aftermarket magazines may provide different capacities, offering more customization options according to the carrier's preferences.

Carry Comfort and Concealability

The Glock 48's design is notably slimmer, owing to its single-stack magazine, which enhances concealability. The reduced width makes the Glock 48 nearly a quarter of an inch thinner than the Glock 19, which can significantly improve comfort, primarily when carried for extended periods. Both models are highly concealable, with many holster options catering to carrying styles.

  • Glock 19: Wider due to double-stack, potentially less comfortable for long-term carry
  • Glock 48: The slimmer profile, increased comfort, and concealability

Each model's dimensions and weight impact the overall carry experience, with the lighter and more compact Glock 48 offering advantages for those who prioritize a minimal imprint.
