Frequently Asked Questions

What are the top 5 modifications to avoid on a Glock for self-defense?

For self-defense Glocks, avoid overly extended magazine releases, DIY barrel porting, excessive slide cuts, improper recoil spring assemblies (too light), and excessively light triggers ('hair triggers'). These can cause malfunctions, reduce reliability, or create safety and legal risks.

Why should I avoid aggressive slide cuts on my Glock?

Aggressive slide cuts remove significant weight, altering the slide's cycling geometry. Without precise tuning of the recoil spring assembly to compensate, the firearm may experience timing issues and malfunctions, compromising reliability.

What are the risks associated with a light trigger on a self-defense firearm?

An excessively light trigger, often called a 'hair trigger,' significantly increases the risk of accidental discharges or unintended double taps, especially under high stress. This poses serious safety hazards and can create substantial legal liabilities.

Can cosmetic engravings on a Glock affect legal defense?

Yes, aggressive or 'edgy' engravings (like skulls or pop-culture symbols) on a carry firearm could potentially be used by prosecutors in court. They might attempt to paint a negative picture of your intent during a self-defense trial.
