Frequently Asked Questions

Which Glock parts should you replace first?

Generally speaking, the smallest components exposed to the most wear and tear will likely be the first to deteriorate. Components like the recoil spring, trigger spring, slide lock spring, and machine catch spring should be examined regularly for signs of wear.

Why should you customize your Glock?

Shooters choose to customize Glocks for a variety of reasons based on their personal preferences and shooting contexts. For instance:

  • Home defense gun owners might add lights or lasers to their handguns for improved accuracy.
  • Competition shooters might modify their barrel or other components for improved shooting performance or reduced carry weight.
  • Concealed carriers might modify their weapon for increased ease of concealment, extended clip capacity, or ease of racking the slide. 

Why choose the Glock 19 instead of another model?

The Glock 19 is one of the most popular models for a few reasons:

  • It’s chambered in 9mm — a widely available, relatively inexpensive round with excellent ballistic performance and lethality for self-defense applications.
  • Its 15-round standard capacity is advantageous in home or self-defense scenarios.
  • It’s a compact build, offering a happy medium between smaller, subcompact pistols and full-size builds (but this is true for multiple Glock models).
  • As one of the most popular models, aftermarket components for the Glock 19 are widely accessible. 

Which parts of a Glock can you customize?

Technically, you can replace just about any part of your Glock handgun with a custom aftermarket part. However, some of the most commonly customized Glock components are:

  • The barrel
  • The slide
  • The trigger
  • The back plate
  • The magazine

Are all Glock 19 parts interchangeable?

While most Glock 19 components are interchangeable, be aware of potential configuration changes between Glock generations. Read your pistol’s manual or specifications carefully before purchase to ensure compatibility with aftermarket parts and accessories.
