True Precision Ultimate Recoil Spring Kit Glock 19 Gen4/Gen5

True Precision's Ultimate Spring Kit is a recoil spring tuning set for the Glock 19. It includes several spring weights so you can match the recoil system to your build instead of living with whatever the gun came with, plus the adapter bushing needed for Gen4, Gen5 and V pistols and their aftermarket copies. The springs themselves work across Glock 19 variants from Gen1 through Gen6.

Spring tuning matters most when something changes at the muzzle or on the slide. A compensator, a suppressor, a lighter slide or a switch in ammo all move the timing, and the right spring weight brings cycling back in line and takes some of the snap out of the recoil impulse. True Precision rates each spring past 20,000 compressions, so a kit lasts through a lot of experimenting.
