Glock launches new models into its slimline series, introducing Modular Optic System configurations for the G43X and G48 pistols. 

The slimline G43X and G48 were announced in 2019, but the pistols are now getting the MOS treatment with an optics-ready, factory-milled slide and slim Glock mounting rail system. It's worth noting, the handguns offer a non-standard MOS footprint requiring micro-reflex optics.

The MOS system looks to cater to the growing market of red dot enthusiasts who wish to improve accuracy and quicken target acquisition. Glock says the MOS paired with the slim build brings the optic closer to the shooter's line of sight, allowing the shooter to use standard Glock sights, instead of tall, back-up sights. 

In addition to offering the non-standard MOS footprint, Glock also uses a non-standard accessory rail for lights. The gunmaker says the rail is positioned to allow for "close alignment to the firearm's bore." The rail is located forward of the trigger guard so shooters can maintain a two-handed grip.

Offering a 10-round capacity, models use Glock's Gen 5 platform, delivering an nDLC finish, reversible magazine catch, and Glock Marksman Barrel. The G48 measures 7.28-inches in overall length with a 4.17-inch barrel and weight sitting around 20-ounces. The G43X measures slightly smaller with an overall length of 6.50-inches and a 3.41-inch barrel. The G43X tips scales at 18.7-ounces.

Glock said the slimline MOS models could easily adapt to the needs of the shooter, whether that be for concealed carry, target shooting or competition

“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,” Shelby Lasater, Director of Marketing, said in a press release. “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.”

Ryan Gresham with Guns & Gear was able to get his hands on the two new MOS models, and touches base on them in the below video with Team GLOCK's increasingly bearded Shane Coley on hand to give the run down.
