True Precision Recoil Spring Tuning Kit - Fits Compensated & Suppressed Glock 19 Gen 6 - Black - GLK19STK-6 - UPC: 719104544258
Product Description
The True Precision GLK19STK-6 Recoil Spring Tuning Kit is a high-performance guide rod and spring system custom-engineered for Glock 19 Gen 6 pistols, as well as aftermarket Gen 6-compatible frames and early Gen 1–3 platforms running muzzle compensators, suppressors, or variable-velocity ammunition. Standard factory captured recoil assemblies are calibrated strictly for uncompensated slides firing standard factory ammunition. When adding a barrel compensator or heavy suppressor, the diverted gas pressure or extra muzzle mass often starves the slide of rearward momentum, leading to extraction or feeding failures. The GLK19STK-6 kit resolves these issues by allowing armorers and shooters to fine-tune slide cycling resistance to match their specific muzzle setup and ammunition load.
At the center of the kit is a billet stainless steel guide rod paired with six calibrated, high-strength chrome-silicon flat-wire recoil springs engineered to deliver consistent performance over 20,000+ compression cycles. The non-captured guide rod design eliminates a common point of failure found in standard assemblies and allows rapid, tool-free spring weight swaps right on the bench or range. Providing a broad spectrum of spring weights—11 lb, 13 lb, 15 lb, 18 lb (OEM standard), 20 lb, and 22 lb—this kit gives shooters complete control over slide velocity, ejection pattern, and muzzle return-to-battery timing.
Ideal for competitive shooting setups, suppressed tactical staging, or custom slide builds, the True Precision GLK19STK-6 kit delivers the mechanical adjustability required to eliminate stovepipes and maximize cycling smoothness on customized 9mm Glock platforms.
*Armorer Bench Notes & Real-World Staging Guidance:
Platform & Muzzle Device Tuning Matrix:
• Primary Compatibility: Glock 19 Gen 6 models and aftermarket copies (also backwards compatible with Glock Gen 1–3 pistols).
• Included Spring Weights: 11#, 13#, 15#, 18# (OEM weight), 20#, and 22# flat-wire chrome-silicon springs.
Tuning & Installation Steps:
1. Unload host firearm, clear chamber, remove magazine, and field strip the slide assembly from the frame.
2. Remove the factory captured recoil spring assembly.
3. Install the desired test spring onto the True Precision stainless steel guide rod (start with a 13# or 15# spring when staging a compensated slide with standard range ammo).
4. Compress and seat the guide rod assembly into the slide nose ring and lower barrel lug crescent notch.
5. Reassemble firearm and perform live-fire testing: If the slide fails to lock back on an empty mag or stovepipes, step down to a lighter spring weight. If muzzle dip is excessive or the slide slams rearward, step up to a heavier spring weight.
