True Precision Recoil Spring Tuning Kit Features The True Precision Recoil Spring Tuning Kit is designed for Glock 19 Gen1 through Gen6 models and compatible aftermarket copies giving owners a wide range of fit across their pistol collection. The kit includes six spring weights 11 13 15 18 20 and 22 pounds allowing shooters to dial in the exact recoil spring rate needed for their specific slide weight ammunition choice or muzzle device. This adjustability is especially useful for compensated or suppressed Glock 19 Gen 4 5 and V pistols where factory spring rates often fail to cycle reliably. Each spring is made from high-strength chrome silicon for consistent long-lasting performance. A stainless steel billet-machined non-captured guide rod is included in the kit replacing the factory guide rod with a more durable precision-made component. An adapter bushing is also included specifically for Gen 4 5 and V Glock pistols and their aftermarket variants ensuring proper fit across those frame generations. True Precision rates these springs for over 20 000 compressions each giving shooters confidence in long-term reliability. Finished in black and made entirely in the USA this kit offers a straightforward way to fine-tune a Glock 19 s cycling for improved reliability and reduced felt recoil.
