The Glock 9mm Gen 5 Semi-Auto Handgun is a modern striker-fired pistol built around Glock's fifth-generation operating system. Chambered in 9x19mm, the Gen5 platform introduced a number of mechanical and ergonomic refinements over earlier Glock generations, including the Glock Marksman Barrel, ambidextrous slide-stop controls, revised internal components, a flared magazine well and a grip design without the finger grooves found on many Gen3 and Gen4 pistols. The result is a straightforward service-style handgun centred on simple controls, durable construction and Glock's established Safe Action operating system. Because Glock produces several Gen5 pistols in 9mm, including full-size, compact and crossover configurations, exact dimensions, barrel length, magazine capacity and sight specification vary by model. The individual model designation should therefore be confirmed from the firearm itself before publishing model-specific measurements.

Glock 9mm Gen 5 Key Features

• 9x19mm Chambering: Built around the widely established 9x19mm cartridge used throughout Glock's Gen5 pistol family.
• Gen5 Platform: Fifth-generation Glock pistols incorporate a revised frame, barrel, slide controls and internal operating components while retaining the fundamental architecture of the Glock Safe Action system.
• Striker-Fired Action: Uses Glock's striker-fired operating system rather than a conventional external hammer, keeping the exterior controls and internal firing mechanism comparatively simple.
• Safe Action System: Glock's Safe Action design incorporates three independent passive mechanical safeties within the pistol's operating system: trigger safety, firing-pin safety and drop safety.
• Glock Marksman Barrel: Gen5 models use Glock's Marksman Barrel, which features revised rifling geometry and barrel construction compared with earlier generations.
• nDLC Surface Treatment: Gen5 slides and barrels use Glock's nDLC surface treatment, providing a hard, corrosion-resistant exterior finish intended for regular handling and service use.
• Ambidextrous Slide Stop Lever: Gen5 pistols incorporate slide-stop controls on both sides of the frame, improving compatibility for left- and right-handed users.
• Reversible Magazine Catch: The magazine-release button can be configured for either side of the grip on compatible Gen5 models.
• No Finger Grooves: Glock removed the moulded finger grooves used on many previous-generation frames, creating a straighter frontstrap profile intended to accommodate a wider range of hand sizes.
• Flared Magazine Well: The lower grip incorporates a subtly enlarged magazine-well opening as part of the Gen5 frame design.
• Modular Backstrap System: Compatible Gen5 pistols use interchangeable backstrap components to alter grip circumference and beavertail configuration.
• Polymer Frame: The frame uses Glock's impact-resistant polymer construction with steel internal rails supporting the slide assembly.
• Steel Slide: A machined steel slide houses the barrel, striker assembly, extractor and recoil system.
• Dual Recoil Spring Assembly: Gen5 9mm models use a captured dual recoil-spring assembly matched to the particular pistol configuration.
• Front Slide Serrations: Many current Gen5 FS configurations incorporate serrations at both the front and rear of the slide. Exact slide configuration varies between specific Gen5 production versions.
• Accessory Rail: The frame incorporates an equipment rail ahead of the trigger guard for compatible accessories where legally permitted.
