Glock G40 G4 MOS 10mm Auto Full-Size Pistol – 10mm

Description

Product Overview

The Glock G40 Gen4 MOS 10mm Auto is a purpose-built, full-size pistol engineered for demanding outdoor applications where power, precision, and reliability are non-negotiable. As Glock’s long-slide offering in the potent 10mm Auto caliber, this model features a 6.02-inch barrel to maximize ballistic performance, making it a premier choice for handgun hunters, backcountry enthusiasts, and competitive sport shooters. The G40 Gen4 MOS (Modular Optic System) integrates a versatile mounting platform for red dot sights directly onto the slide, a critical feature for rapid target acquisition in variable field conditions. With a standard magazine capacity of 15 rounds, it balances formidable firepower with the rugged dependability synonymous with the Glock name. This pistol is designed for the shooter who requires a semi-automatic handgun capable of ethical takedowns of game at extended ranges and dependable performance in harsh environments.

Key Features

• 10mm Auto Chambering: Provides a significant power advantage over standard service calibers, offering superior energy, flatter trajectory, and enhanced terminal performance for hunting and outdoor defense.
• MOS (Modular Optic System) Platform: The slide is precision-milled to accept a variety of popular micro red dot sights (with separate adapter plates), allowing for a custom, co-witnessed optic setup without the need for aftermarket machining.
• 6.02-Inch Barrel: The extended, cold-hammer-forged barrel with a nitride finish ensures exceptional accuracy, increases muzzle velocity for improved 10mm ballistics, and contributes to a reduced felt recoil impulse.
• Gen4 Enhanced Ergonomics: Features interchangeable backstraps (Large, Medium, Small, and Beaver Tail) to customize grip circumference and feel. The textured grip surface and reversible magazine catch enhance control and shooter comfort.
• 15-Round Standard Capacity: Offers ample firepower for extended range sessions or multiple-target scenarios in the field, housed in a durable, steel-reinforced polymer magazine.
• Robust Nitride Finish: The nPVD surface treatment on all metal components provides exceptional corrosion resistance and durability, protecting the pistol from moisture, sweat, and the elements encountered during outdoor use.

Performance & Applications

The Glock G40 Gen4 MOS excels in specific, demanding roles where its combination of caliber, sighting system, and barrel length provides a tangible advantage. Its design directly addresses the needs of specialized shooters.

Handgun Hunting: This is the G40’s primary domain. The 10mm Auto cartridge, when loaded with appropriate full-power, heavy-weight hunting projectiles, delivers ethical takedown energy for medium game at handgun distances. The extended barrel maximizes this potential, while the MOS system allows for the mounting of a magnified red dot or a standard optic with a clear, precise point of aim, crucial for making clean shots. The platform has proven effective for hunting species such as whitetail deer, feral hogs, and black bear within its effective range.

Backcountry & Trail Defense: For those working or recreating in remote areas with potential predator threats, the G40 serves as a powerful and reliable defensive tool. The 10mm Auto is a widely respected caliber for defense against large, dangerous animals. The pistol’s reliability in adverse conditions, high capacity, and the rapid threat engagement enabled by a mounted red dot sight make it a serious option for wilderness protection.

Practical Competition Shooting: In action pistol sports like USPSA or IDPA’s “Backup Gun” (BUG) division where allowed, or in specific 10mm-focused matches, the G40 offers a soft-shooting, high-capacity, and fast-cycling platform. The minimal recoil impulse from its size, combined with the speed advantage of a red dot, allows competitive shooters to manage the 10mm’s power effectively for fast, accurate follow-up shots.
