We acquired this PREOWNED G21 in a trade.  It's in excellent condition.  The slide was milled right here at Wraith Precision and it comes with a brand new Holosun 407C X2 Red Dot.  It has been cleaned, oiled, rigorously safety-checked and given the gunsmith's seal of approval.

The Glock 21 is remarkable for its accuracy and light recoil. It features Glock's Safe Action system which provides a consistent trigger pull from the first to the last round. The three automatic independently operating mechanical safeties are built into the fire control system of the pistol. All three safeties disengage sequentially as the trigger is pulled and automatically reengage when the trigger is released. The frame is made of polymer with hardened steel guides. It features an ideal grip angle and low weight. The slide stop lever and the magazine catch are easily operated with the shooting hand. The advanced surface treatment of the slide results in optimal hardness by considerably reducing wear and tear and it makes it corrosion resistant, even when operating in saltwater conditions. The matte surface minimizes light reflection.
