Do Glock Gen 6 Models Fit Glock Gen 5 Holsters?

As anticipation continues to build around future Glock Gen 6 models, one of the most common questions from concealed carry users and range enthusiasts is simple:

Will Glock Gen 6 models fit existing Glock Gen 5 holsters?

While official specifications for future Glock Gen 6 models may vary by platform and production changes, early compatibility expectations suggest that many Glock Gen 6 pistols will maintain overall dimensions similar to Gen 5 counterparts — meaning many existing Gen 5 holsters may still provide proper fitment.

At STS Concealment, we design our holsters with precision molding and real-world carry performance in mind. Because Glock typically maintains consistent frame dimensions across generations, many Gen 5-compatible holsters are expected to remain compatible with equivalent Gen 6 models unless major frame, slide, rail, or trigger guard changes are introduced.

Expected Compatibility Between Glock Gen 5 & Gen 6

Many Glock owners are familiar with cross-generation compatibility already. Similar to how Gen 4 and Gen 5 pistols often share holster fitment, Glock Gen 6 models are expected to follow many of the same exterior dimensions for:

• Slide width
• Trigger guard shape
• Rail dimensions
• Frame profile
• Overall footprint

Because of this, many STS Concealment Glock Gen 5 holsters may also accommodate comparable Glock Gen 6 models.

What Could Affect Holster Fitment?

Even minor design revisions can impact retention and fitment. Potential factors include:

• Updated frame texturing
• Rail modifications
• Slide contour changes
• Ambidextrous control redesigns
• New optic-ready configurations
• Light or laser attachments

As always, weapon-mounted lights and lasers dramatically change holster compatibility.

Important Fitment Note

Unless specifically stated, STS Concealment holsters are not designed to fit models equipped with aftermarket lights, lasers, or laser/light combinations.
