Gen5 Features

The Glock 45 Gen5 includes:

• Glock Marksman Barrel (improved accuracy)
• Ambidextrous slide stop lever
• Reversible magazine release
• Flared magazine well for quicker reloads
• Front slide serrations on current production models
• Improved nDLC finish on the slide and barrel
• No finger grooves
• Enhanced Gen5 grip texture
• Safe Action trigger system with three passive safeties

Why the “45”?

Despite its name, the Glock 45 is chambered in 9mm, not .45 ACP. The model number is simply Glock’s product designation.

Its layout combines:

• Compact Glock 19-length slide
• Full-size Glock 17 grip

This offers:

• Faster reloads
• Full firing grip
• Good balance and controllability
• Easier slide carry than a full-length pistol

Magazine Compatibility

The Glock 45 uses full-size double-stack 9mm magazines, including:

• Factory 17-round magazines (standard)
• 19-round magazines
• 24-round magazines
• 31-round magazines
• 33-round magazines

Because the frame is full-size, Glock 19 magazines are too short to fit properly.

Performance

Advantages

• Excellent reliability
• Full-size grip provides excellent control
• Compact slide is quick to draw
• Low felt recoil
• Excellent practical accuracy
• Huge aftermarket support
• Easy maintenance and field stripping

Considerations

• The full-size grip can make concealed carry more difficult than a Glock 19.
• Larger grip may print more under light clothing.
• Slightly heavier than slimline carry pistols.

Common Uses

The Glock 45 Gen5 is well suited for:

• Duty or service carry
• Home defense
• Range shooting
• Defensive training
• Open carry
• Concealed carry (with the right holster and clothing)

Many owners describe it as one of Glock’s best-balanced shooting pistols because of its crossover design.
