Radian Weapons AG19ROD Guide Rod | G19/19X/G45 | Nitride

The Radian Weapons Compressor Quick-Tune Guide Rod is a screwless, adjustable guide rod assembly designed for Glock G19, G19X and G45 pistols. It is constructed from heat-treated 17-4 stainless steel and finished with a durable nitride coating for corrosion resistance. The design uses a dovetail interface captured by the spring and flutes along the rod to reduce friction and promote smoother cycling. The kit includes three flat-wire springs in different weights and hardware for Gen3/Gen4/Gen5 compatibility.

Common applications include tuning an everyday-carry or concealed-carry pistol for desired recoil characteristics and optimizing a range or competition pistol for consistent cycling and shooter preference.
