Glock announced the addition of not just one but two new models to its Slimline series of self-defense handguns in 2020. The new G43X and G48 MOS pistols combine the benefits of Glock's Modular Optic System (MOS) with the concealable and carry-ready configuration offered by its Slimline handguns. The new guns also feature a Picatinny accessory rail.

“Engineered with the GLOCK perfection promise, the two new models are the first Slimline pistols to offer an MOS option and are ideal for shooters everywhere,” said Shelby Lasater, GLOCK, Inc. director of marketing. “The versatility of the Slimline MOS models give them the adaptability and ease of use for concealed carry, target shooting, law enforcement, and competition which make them a new favorite.”

Introduced in 2019, Glock's G43X and G48 handguns expanded the company's Slimline series, giving consumers increased capacity and sight radius while maintaining an easily concealed and carried design. The G43X built on the success of Glock's original G43 by offering a lengthened frame that accepted an enlarged magazine with increased capacity.

At the same time, the Glock G48 featured the same enlarged frame found on the G43X combined with a lengthened slide, giving shooters greater accuracy potential, thanks to the lengthened sight radius. The increased slide also allowed Glock to increase barrel length, which provides greater ballistic performance compared to shorter configurations.

Glock offered its MOS system first in full- and duty-size handguns, giving handgunners an edge in rapid target acquisition and accuracy, thanks to the single-plane design of a mounted red-dot sight. The slimmer profile of the G43X and G48 presented a challenge, though, because the footprint offered by the top of the slide is slimmer than that included on Glock's traditional double-stack semi-automatics.

The MOS system used on the Glock Slimline pistol series is, functionally, the same setup found in its larger siblings. However, given its reduced footprint, the Slimline MOS models require the use of special micro reflex optics, like the Shield Sights RMSc. Both the G43X and G48 MOS models also incorporate all the enhancements found on Glock's Gen 5 series of guns, including an nDLC finish, reversible magazine catch and a match-grade Glock Marksman Barrel.
