This True Precision recoil spring tuning kit is built for the Glock 19 Gen 4, Gen 5 and V and their aftermarket copies, and it includes the adapter bushing those generations need. The kit is also compatible with Glock 19 Gen 1-6 pistols. Use it to tune cycling on a compensated or suppressed Glock 19, a lighter or heavier slide, or a change in ammo.

The springs are high-strength chrome silicon, rated for more than 20,000 compressions each. A billet-machined stainless steel guide rod (non-captured) is included, so you can swap spring weights without buying a new rod assembly.

Features:

• Designed for Glock 19 Gen 1-6 models and aftermarket copies
• Adapter bushing for Gen 4, Gen 5 and V included
• High-strength chrome-silicon springs
• Stainless steel, billet-machined non-captured guide rod
• Includes 11 lb, 13 lb, 15 lb, 18 lb, 20 lb and 22 lb springs
• 100% made in the USA

Start with the spring weight closest to your current setup and adjust one step at a time. Function-check with your carry ammo after each change, and confirm reliable lock-back on an empty magazine before you carry or compete with it.
