A slide devise for facilitating grasping and pulling a pistol slide rearward during various pistol operations. The slide device facilitates pulling back the pistol slide utilizing relatively little force. The device includes an adaptor and a rack plate interconnected by a sliding dovetail joinery.

The rack adaptor has an integral interface shoe, which seats within a complementary channel in the rack plate. The rack plate has a pair of opposed side protrusions or wings that are configured to fit or be engaged by the fingers or hand of the user, so as to allow the user to easily pull the pistol slide rearward.
