<p>The GLOCK® 41 Gen4 MOS 45 ACP Semi-Auto Pistol is the optics-ready, full-size, long-slide competition offering from GLOCK chambered in the large .45 ACP. The G41 comes with finger grooves, a right-hand-only slide stop, and reversible magazine release. For several years now, many have been getting their slides milled out by gunsmiths to cleanly attach a sight to their pistol. The MOS (Modular Optic System) has a slide cut out and 4 plates to accommodate just about any popular RDS (Red Dot Sight). Some still prefer a custom cut, while many prefer the ease of use with the MOS system. The slide and barrel feature GLOCK's Tenifer coating, an insanely durable finish. GLOCK's MBS (Modular Backstrap System) allows you the ability to add or remove additional backstop pieces, including a beaver tail for those with larger hands. This eliminates slide bite. In front of the trigger guard you'll also receive an integral accessory rail for a wide variety of light and laser accessories.</p> <ul> <li>Chambered in .45 ACP</li> <li>Full-size, competition long-slide pistol</li> <li>Modular Backstrap System</li> <li>MOS optics ready</li> <li>4th generation</li> <li>Right-hand-only slide stop</li> <li>Reversible mag release</li> <li>Glock Tenifer slide</li> <li>Finger grooves on front strap</li> <li>Integral accessory rail</li> </ul>
