The Glock 41 Gen 4, denoted by the model number UG4130103MOS, is a practical yet tactical 45 ACP pistol that has been engineered to perfection, intending to optimize the sight radius while enhancing weight distribution and balance. It comes with a longer barrel and slide, which function to reduce muzzle flip and recoil sensation, making it a superior choice for competition or official duty usage. This model features the Glock Modular Optic System (MOS), which greatly simplifies the process of mounting popular optics, saving the trouble and cost of hiring custom slide machinists. The MOS allows the use of four different plate options, adjusting to the specifications of some of the top-rated optic manufacturers in the industry. When not in use, a cover plate can be utilized. The standout attribute of MOS is the unique option of adding tall iron sights, enabling the optic and the iron sights to co-witness. Do note, the modular sight is not included with the pistol but the necessary bracket for its mounting is.
