True Precision Recoil Spring Tuning Kit - Fits Compensated & Suppressed Ruger RXM - Black - RXMSTK - UPC: 719104544265
Product Description
The True Precision RXMSTK Recoil Spring Tuning Kit is a high-performance guide rod and spring assembly custom-engineered for the Ruger RXM pistol, as well as cross-compatible Glock Gen 1–3 and Gen 6 platform variants 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 failure-to-eject (stovepipe) or failure-to-feed malfunctions. The RXMSTK kit resolves these issues by enabling armorers and shooters to fine-tune slide cycling resistance to match their specific muzzle setup and ammunition load.
At the core of the kit is a non-captured billet stainless steel guide rod paired with six (6) 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 RXMSTK kit delivers the mechanical adjustability required to eliminate stovepipes and maximize cycling smoothness on customized 9mm handguns.
*Armorer Bench Notes & Real-World Staging Guidance:
Platform & Muzzle Device Tuning Matrix:
• Primary Compatibility: Ruger RXM pistols and RXM pattern copies (also backwards compatible with Glock Gen 1–3 and Gen 6 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.
