About the Glock 20
The Glock 20 is a full-size, striker-fired pistol chambered in 10mm Auto, built with a reinforced frame and slide to handle the pressures of that cartridge. It is often associated with hunting, outdoor carry, and use where a more powerful cartridge is desired.
The pistol has progressed through the same general generational changes as other Glock models, with Gen3 and Gen4 versions being the most commonly encountered, along with a Gen5-based SF-style variant in some configurations.
Because 10mm Auto is a less common defensive chambering than 9mm, buyers evaluating a Glock 20 often consider magazine and ammunition availability alongside standard condition factors.

Valuation
What affects Glock 20 value
We do not publish a price chart. These are the characteristics that determine what a specific example evaluates at.
Factor 1
Generation and frame configuration
Gen3, Gen4, and SF-frame versions differ in ergonomics and features, and identifying the correct configuration is part of evaluation.
Factor 2
Caliber-specific demand
Because 10mm Auto is a less common defensive chambering than 9mm, buyers consider magazine and ammunition availability as part of overall demand.
Factor 3
Factory versus aftermarket parts
Original barrel and internal components as opposed to aftermarket replacements affect how original a pistol is relative to factory configuration.
Factor 4
MOS optic-ready slides
Optic-cut slides are assessed as a distinct configuration from standard slides.
Factor 5
Field or holster wear
Outdoor carry and hunting use can leave finish wear that buyers weigh against a lightly used example.
Factor 6
Included magazines and case
Factory magazines, box, and manual contribute to overall completeness.
