Choosing the Right Caliber

The Glock 19 Gen 4 is available in two popular calibers: 9mm and .40 S&W. Each caliber has its own advantages and considerations:
9mm
- Ammunition Availability: 9mm ammunition is widely available and often more affordable than other calibers.
- Recoil Management: 9mm rounds generally produce less recoil, making it easier to control the pistol and maintain accuracy.
- Capacity: The 9mm version of the Glock 19 Gen 4 typically offers a higher magazine capacity, providing more rounds for self-defense or competition shooting.
.40 S&W
- Power: .40 S&W rounds deliver more power and energy, making them suitable for situations where greater stopping power is required.
- Penetration: These rounds offer better penetration, which can be crucial for certain self-defense scenarios.
- Recoil: The increased power of .40 S&W rounds results in a higher recoil, which may affect accuracy for some shooters.
When choosing the caliber, consider your primary purpose for the pistol, your shooting experience, and personal preferences. It's always a good idea to try out both calibers if possible to find the one that suits your needs best.
Customizing Your Glock 19 Gen 4

One of the great advantages of the Glock 19 Gen 4 is its adaptability. You can customize various aspects of the pistol to enhance its performance and fit your shooting style. Here are some popular customization options:
Sights
Upgrading the sights is a common modification to improve accuracy and visibility. You can choose from a wide range of options, including:
- Tritium Night Sights: These sights provide a bright, illuminated dot, making them ideal for low-light conditions. They offer quick target acquisition and improved accuracy.
- Fiber Optic Sights: Fiber optic sights use light-gathering fibers to create a bright, visible front sight. They are excellent for fast target acquisition and are popular among competitive shooters.
- Red Dot Sights: Red dot sights project a red dot onto the lens, allowing for rapid target acquisition. They are highly versatile and can be used for both close-quarters combat and long-range shooting.
Grip Enhancements
To further improve your grip and control, consider the following grip enhancements:
- Grip Tape: Applying grip tape to the grip surface can enhance your grip, especially in wet or sweaty conditions. It provides a more secure hold and reduces the chances of slippage.
- Grip Plugs: Grip plugs are small, textured inserts that fit into the front and back of the grip. They add texture and improve the overall grip, making it easier to maintain control during recoil.
- Backstrap Modifications: If you prefer a different grip size, you can swap out the backstraps to find the perfect fit. This modification ensures a comfortable and natural shooting experience.
Trigger Modifications
For an even crisper and lighter trigger pull, consider these trigger modifications:
- Trigger Shoe: A trigger shoe extends the trigger surface, providing a larger area to press. This modification can reduce trigger pull weight and improve your overall shooting performance.
- Trigger Spring: Replacing the factory trigger spring with a lighter one can reduce the trigger pull weight, making it easier to pull the trigger smoothly.
- Trigger Stop: A trigger stop prevents over-travel, ensuring a clean and consistent break on the trigger. It helps maintain accuracy and control during rapid fire.
Upgrading Your Magazine Capacity

If you require additional rounds for self-defense or competition shooting, upgrading your magazine capacity is an excellent option. Glock offers extended magazines for the 19 Gen 4, providing a higher round count:
- Standard Capacity: The standard magazine capacity for the Glock 19 Gen 4 is 15 rounds. This is suitable for most situations and offers a good balance between capacity and concealability.
- Extended Capacity: Extended magazines can hold up to 17 rounds, giving you a few extra shots. These magazines are slightly longer but still fit comfortably in most holsters.
- High Capacity: For those who require maximum capacity, high-capacity magazines can hold up to 33 rounds. These magazines are longer and may require a different holster setup.
Holster Options

Choosing the right holster is essential for comfortable carry and quick access to your pistol. Here are some popular holster options for the Glock 19 Gen 4:
IWB (Inside the Waistband) Holsters
- Concealment: IWB holsters are designed to be worn inside the waistband, providing excellent concealment for everyday carry.
- Comfort: They offer a comfortable and secure carry position, distributing the weight of the pistol evenly.
- Draw Speed: With proper training, drawing from an IWB holster can be quick and efficient, making it suitable for self-defense situations.
OWB (Outside the Waistband) Holsters
- Accessibility: OWB holsters are worn outside the waistband, offering easy access to the pistol.
- Comfort: They can be more comfortable than IWB holsters for some individuals, as they don't require the pistol to be carried directly against the body.
- Concealment: OWB holsters may be less concealable, especially with bulkier clothing, but they are a popular choice for open carry or range use.
Maintenance and Cleaning

Proper maintenance and regular cleaning are crucial to ensure the reliability and longevity of your Glock 19 Gen 4. Here are some maintenance tips:
- Field Stripping: Familiarize yourself with the field stripping process to clean and maintain your pistol. Regular field stripping helps remove dirt, debris, and residue, keeping your Glock in optimal condition.
- Lubrication: Apply a high-quality gun lubricant to moving parts, such as the slide and trigger, to reduce friction and ensure smooth operation.
- Storage: When not in use, store your Glock in a safe and secure location. Consider using a gun case or safe to protect it from dust, moisture, and unauthorized access.
