Glock G40 Generation 4 Modular Optic System 10mm Auto 6.02 in 15+1 Matte Finish

The Glock G40 Gen4 MOS Competition in 10mm Auto brings the Gen4 series� durability and modular optics system together with a long 6.02" cold hammer forged steel barrel and a matte black serrated steel slide with MOS cuts to accept red dot optics, making it well suited for competition stages, hard-hitting hunting scenarios and serious range work where sight speed and barrel harmonics matter. The black polymer frame with Picatinny rail and interchangeable backstraps delivers a controllable grip and accessory mounting for lights or lasers, while the rough-texture finger grooves and serrated trigger guard help maintain control during rapid strings. With a 15+1 capacity, safe-action style firing pin/trigger block safety and DAO action, the pistol balances follow-up shot speed with consistent trigger behavior; the adjustable sight configuration pairs with the MOS cut to let shooters choose irons or optics depending on match rules or field conditions. Included items such as a mag loader, cleaning set, case, backstrap set and cable lock make it range-ready out of the box, and note that an FFL transfer is required for purchase.
