The Radian Weapons Compressor Quick-Tune Guide Rod for Glock 19/19X/45 is a screwless, adjustable guide rod that lets you change recoil spring weight without thread locker (Radian part no. A-G-19-ROD). Most adjustable guide rods retain the spring with a cap screw, and loose screws are a common complaint; the Compressor captures a dovetail cap with the spring itself. Flutes along the rod let the spring move with less friction, and the heat-treated rod carries a nitride finish. It is a straightforward tuning upgrade for a Glock 19 owner who wants to try different spring weights. Radian Weapons ships the kit in black with three springs.

Key Specifications

• It fits the Glock 19, 19X and 45, the models named on Radian’s own listing for this part number.
• The design is screwless, with a dovetail interface captured by the spring, which avoids the loose cap screws common to other adjustable rods.
• The rod is fluted along its length so the spring moves with less friction for smoother cycling.
• The rod is heat treated, which Radian pairs with its finish for a durable part.
• The finish is nitride, slick and corrosion resistant.
• The color is black.
• Three uniquely weighted springs are included, so you can tune the feel without buying more parts.
• The kit also includes a Compressor bushing, cap and Gen 3 washer, the pieces that complete the assembly.
• A Compressor tool is in the box, which can help hold the spring down when removing and installing the cap.
• Changing springs does not require thread locker, since the dovetail cap locks without a screw.
