True Precision Glock 19 Gen6 Recoil Spring Tuning Kit

A comp or a suppressor changes the timing of a slide, and the spring that came in the gun rarely suits the new setup. This kit covers the Glock 19 Gen6 with a set of springs in different weights so the pistol can be tuned to the load and the muzzle device actually on it, rather than the one the engineers assumed.

The springs are chrome silicon and rated past 20,000 compressions each. They ride on a billet machined stainless steel guide rod that is not captured, which makes swapping weights a bench job rather than a project. True Precision also lists it as compatible with Gen1 through Gen3 pistols.
