"The Beretta 92G Elite LTT Semi-Auto Pistol with Langdon Trigger Job and RDO Slide is built in a partnership between Beretta and Ernest Langdon of Langdon Tactical, a premiere custom shop known for their top tier modifications on Beretta 90-series pistols. This Ultimate 92 Package gets you into an optic-ready M9A3 slide paired with an M9A1 frame with a Vertec grip. The slide features 5 new components and a custom mounting plate in order to get the red dot sight lower. When paired with a RMR (RMR not included), the dot above center of bore comes in at .85"", which is lower than most milled striker-fired systems. The slide also features front and rear angled cocking serrations, a fiber optic front sight, and a ""G"" decocker. A stainless 4.7"" barrel comes with a target crown. You'll also receive a stainless steel guide rod and beveled rear slide. The G model only decocks and does not have a traditional ""safe on"" mode. When decocked the lever simply flips back up into the fire position after returning the trigger from single-action mode to double-action mode. This model features LTT's trigger work features polishing and stoning of contact points, an upgraded trigger bar, and a 13# chrome silicon hammer, trigger return, and sear springs. G10 LTT/VZ Grips add excellent ergonomics and grip function to the firearm. You'll also receive front strap and back strap checkering, a skeletonized hammer, Hex head grip screws, a beveled magazine well, D-model hammer spring, flush main spring cap, and an oversized mag release button. A Picatinny accessory rail is also found on the M9A1 frame.
