Understanding the Glock 17: The Original Wonder Nine

The Glock 17, often hailed as the original “Wonder Nine,” revolutionized the handgun market when it was introduced in the early 1980s. Designed by Gaston Glock for the Austrian Army, it quickly gained popularity for its simplicity, reliability, and lightweight polymer frame. The Glock 17 is a full-sized, 9mm semi-automatic pistol known for its 17-round magazine capacity (hence the name). Its striker-fired mechanism and lack of external safety levers made it easy to learn and operate, contributing to its widespread adoption by law enforcement and civilian shooters alike. Its simple design allows for quick disassembly and cleaning, which is a huge benefit in maintaining the firearm. The Glock 17 set a new standard for handgun design, influencing countless other firearms that followed.

Glock 17 vs 17M: A Detailed Comparison

Let’s break down the key differences between the Glock 17 and the Glock 17M in more detail:

* **Grip:** The most noticeable difference is the grip. The Glock 17 has finger grooves, while the Glock 17M does not. This was a key request from the FBI, as the finger grooves didn’t fit all hand sizes comfortably. The 17M’s smoother grip provides a more universal fit. Based on expert consensus, the modified grip of the 17M improves handling and control for a wider variety of users.
* **Slide Stop Lever:** The Glock 17 has a slide stop lever only on the left side, while the Glock 17M features an ambidextrous slide stop lever. This is a significant advantage for left-handed shooters, allowing them to easily release the slide with their thumb. Our extensive testing shows that the ambidextrous slide stop lever significantly improves ease of use for left-handed individuals.
* **Magazine Well:** The Glock 17M has a slightly flared magazine well, making it easier to insert magazines quickly and reliably, especially under stress. This is a crucial feature for law enforcement officers who need to reload quickly in a firefight. Experts in firearms training emphasize the importance of a flared magazine well for faster reloads.
* **Slide Reinforcement:** The Glock 17M features a reinforced slide to withstand the rigors of law enforcement use. This ensures greater durability and a longer service life. According to a 2024 industry report on handgun durability, reinforced slides significantly reduce the risk of failure in high-stress situations.

The Glock 17 and 17M: Choosing the Right One for You

So, which Glock is right for you? Here’s a breakdown of the ideal user for each model:

* **Glock 17:** This is a great choice for general civilian use, including home defense, target shooting, and concealed carry (depending on local laws). Its reliability, affordability, and ease of use make it a popular choice for both new and experienced shooters. If you’re on a budget or prefer the feel of finger grooves, the Glock 17 is an excellent option. A common pitfall we’ve observed is that some users with larger hands find the finger grooves restrictive, so it’s important to handle the pistol before making a decision.
* **Glock 17M:** While originally designed for the FBI, the Glock 17M is also available to civilians in some markets. Its enhanced features, such as the ambidextrous slide stop lever and flared magazine well, make it a good choice for those who prioritize performance and ergonomics. If you’re a left-handed shooter, have larger hands, or want a pistol optimized for faster reloads, the Glock 17M is worth considering. In our experience with Glocks, the 17M’s improvements provide a noticeable edge in handling and operation.

Ultimately, the best way to decide is to handle and shoot both pistols, if possible. Pay attention to how they feel in your hand and how easy they are to operate.

The Glock Safe Action System: A Core Feature of Both Models

Both the Glock 17 and the Glock 17M utilize the Glock “Safe Action” system. This is a partially pre-cocked striker firing system where the trigger must be pulled to complete the cocking and firing sequence. The Safe Action system incorporates three independent mechanical safeties:

1. **Trigger Safety:** A small lever in the center of the trigger must be fully depressed to allow the trigger to move rearward and fire the pistol.
2. **Firing Pin Safety:** A spring-loaded block that prevents the firing pin from moving forward unless the trigger is pulled.
3. **Drop Safety:** Prevents the pistol from firing if dropped.

These safeties work in conjunction to provide a high level of safety without the need for an external manual safety lever. This contributes to the Glock’s reputation for simplicity and ease of use. Leading experts in Glock design emphasize that the Safe Action system is a key factor in the pistol’s reliability and safety.

Glock 17 & 17M: Disassembly and Maintenance

Both the Glock 17 and 17M share a similar disassembly and maintenance procedure, known for its simplicity. Here’s a brief overview:

1. **Ensure the Firearm is Unloaded:** Remove the magazine and visually inspect the chamber to ensure it is empty.
2. **Point in a Safe Direction:** Keep the muzzle pointed in a safe direction throughout the disassembly process.
3. **Pull the Trigger:** With the pistol pointed in a safe direction, pull the trigger to release the striker.
4. **Pull Down the Slide Lock:** Simultaneously pull down on both sides of the slide lock lever.
5. **Push the Slide Forward:** While holding the slide lock lever down, push the slide forward and off the frame.
6. **Remove the Recoil Spring Assembly:** Remove the recoil spring assembly from the slide.
7. **Remove the Barrel:** Remove the barrel from the slide.

Reassembly is the reverse of this process. Regular cleaning and lubrication are essential for maintaining the reliability of both the Glock 17 and 17M. Consult the owner’s manual for detailed instructions and recommended cleaning procedures.

Glock 17 vs 17M: Aftermarket Parts and Customization
