Glock 41 Gen4 MOS.

The G41 Gen4 is a "practical/tactical" .45 AUTO caliber pistol designed to maximize sight radius while improving weight distribution and balance. The longer barrel and slide help to reduce muzzle flip and felt recoil while the longer sight radius provides more accuracy for competition or duty use. The G41 Gen4 comes with all the standard features of the GLOCK Generation 4 pistol group, including the Modular Back Strap design, Gen4 rough textured frame surface and dual recoil spring assembly. Trigger distance: 72.5 mm / 2.85 inch. Trigger travel: 12.5 mm / .49 inch. Barrel distance: 20 mm / 0.79 inch. Barrel Profile: right hand twist; octagonal. Standard Trigger Pull: ~5.62 lbs. Muzzle Velocity: 853 fps. Muzzle Energy: 347 fps. The slide is constructed of gas-nitrate-treated steel with a matte-black finish. GLOCK engineers have developed the GLOCK Modular Optic System (MOS) to simplify mounting of popular optical sights without costly custom machining of the pistol’s slide. The GLOCK MOS allows the shooter to mount the sight of their choice, easily and quickly using only a few tools.  The versatility of the system makes changing optics easy.  The shooter is not locked into one optic since switching from one sight to another is as simple as removing the old sight, removing and reinstalling the correct adapter plate, then mounting the new sight. The MOS is offered with five different plate options to comply with the specifications of some of the most trusted optic manufacturers in the industry. The advantages of optical sights mounted using the MOS are increased speed of target acquisition and target transition for faster times in competition, and improved accuracy at both long and short range. Optical sights are popular in competitive shooting and are becoming increasingly popular for concealed carry, home defense and target shooters.
