The Glock 43X MOS (UPC 764503064999) is the ultimate solution for shooters who refuse to compromise between concealability and performance. Part of the Slimline series, this 9mm pistol features the "A-Cut" slide, factory-milled for the Modular Optic System (MOS). This allows you to easily mount popular micro-red dots like the Shield RMSc or Holosun 507K without the need for custom gunsmithing. Combining a subcompact slide length with a full-size grip, the G43X offers a 10+1 capacity in a profile that won't imprint through your clothing.

The Perfect Balance of Size and Capacity

What sets the G43X MOS apart from the standard 43X is the addition of the GLOCK Slim Mounting Rail, allowing for the attachment of tactical lights and lasers—a must-have for a modern home defense or everyday carry setup. The frame features a built-in beaver tail to prevent slide bite and a match-grade Glock Marksman Barrel (GMB) for increased accuracy right out of the box. The "A-Cut" slide also features front serrations, giving you a positive grip for press-checks or clearing malfunctions even in adverse conditions.

Reliability You Can Trust

Shooters often ask if the slim frame makes the G43X harder to control; however, the balanced grip provides enough surface area for a full purchase, making it significantly more comfortable than smaller pocket pistols. It features the legendary Safe Action system that Glock is famous for, ensuring it only fires when you intend it to.
