Glock 43X, 9mm, 3.41" Threaded Barrel, 2- 15rd Magazines, Optics Ready, Pistol The Glock G43X MOS is a slim 9mm pistol that combines a compact-size grip with a subcompact-length slide, a factory optic-ready interface, and a threaded barrel. This black configuration is built around the Glock Safe Action system and gives shooters a narrow carry profile without giving up a full firing grip, an accessory rail, or the flexibility to add a compatible micro red dot. This exact package includes a 3.41-inch black steel barrel threaded 1/2x28 RH and two 15-round Glock Slimline magazines. With a loaded magazine and one round in the chamber, the pistol provides a 15+1 capacity. An optic is not included, and adapter plates are not included. Choose the exact G43X MOS configuration you need. Order this threaded, 15-round package from BattleHawk Armory for a compact pistol that is ready for a compatible optic and muzzle device. 3.41-Inch 1/2x28 RH Threaded Barrel The 3.41-inch steel barrel is the defining feature of this G43X MOS variant. Its 1/2x28 right-hand thread pattern provides a defined mounting interface for compatible 9mm suppressors, compensators, and other muzzle devices. Confirm the selected device is rated for the caliber, thread pattern, and host pistol before installation. A threaded compact pistol gives the shooter room to configure the muzzle without replacing the barrel. The black barrel finish coordinates with the black slide and frame for a consistent appearance. Any attached device can change overall length, balance, cycling behavior, and holster fit, so the complete setup should be tested with the intended ammunition. RMSc Slimline MOS Optic Interface The G43X MOS slide is cut for the Glock Slimline MOS interface, which accepts RMSc-pattern micro optics directly when the optic and mounting screws match the factory cut. This keeps a compatible sight close to the slide and supports a compact sighting package suited to the pistol's narrow profile. No optic is included with SKU UX4350203FRMOSTB. Adapter plates are also sold separately when a selected sight does not mount directly to the standard Slimline MOS cut. Confirm the optic body, screw length, and mounting instructions before installation. The slide also retains fixed iron sights, giving the pistol a complete sighting system before an electronic sight is added. Two 15-Round Glock Slimline Magazines Two 15-round magazines are included, providing a second magazine for training, range use, or a complete carry setup. Each magazine holds 15 rounds of 9mm ammunition, and the pistol supports one additional chambered round for the stated 15+1 capacity. Glock's 15-round Slimline magazine uses a metal double-stack design engineered for the G43X and G48 while retaining the standard magazine catch. The package does not require an aftermarket magazine catch. Capacity restrictions vary by location, so confirm that this configuration is legal for the intended destination before ordering. Slim Frame, Accessory Rail, and Safe Action System The G43X pairs a slim polymer frame with a compact grip length and an integrated beavertail. The narrow frame is intended to reduce bulk while still allowing a secure firing grip. An integrated accessory rail provides a mounting point for a compatible compact light or laser, with fit determined by the dimensions and mounting system of the selected accessory. Front and rear slide serrations provide textured contact points for slide manipulation. The reversible magazine catch supports right- or left-hand setup, while the Glock Safe Action system uses three passive safeties that disengage as the trigger is pressed and re-engage when it is released. The pistol has no separate manual thumb safety.
