Description

OEM parts and accessories are made with the same attention to detail and quality as the ultra-reliable pistols. From firing pins to trigger springs, nothing keeps you running like OEM parts.

Glock OEM Trigger Spring Gen 1-4 — SP00350

The factory-original stainless steel trigger spring that maintains Glock’s precise 5-pound pull weight across all Gen 1–4 models.

The trigger spring is one of the smallest parts in your Glock — and one of the most consequential. It controls the return force applied to the trigger bar, which directly shapes your trigger pull weight, reset crispness, and overall feel shot after shot. When this spring wears, weakens, or is damaged during a trigger job gone wrong, the entire shooting experience suffers. The Glock OEM Trigger Spring SP00350 restores it to factory specification: genuine stainless steel, precise 5-pound tension, the exact same part Glock installs on the production line.

No aftermarket approximation. No guessing on spring rates. The real thing, at $9.99 with free shipping.

What the Trigger Spring Actually Does

The SP00350 is the coil spring that tensions the trigger mechanism inside the trigger housing. It works in concert with your connector and safety spring to deliver Glock’s characteristic trigger feel — a smooth takeup, a defined wall, a clean break, and a positive reset. Specifically, it:

• Sets trigger pull weight — the standard SP00350 delivers the factory 5-pound pull specification Glock builds to for Gen 1–4 pistols
• Controls trigger return speed — ensures the trigger returns fully forward after each shot for reliable reset
• Works with your existing connector — pairs with any standard, dot, or minus (-) connector without modification
• Differentiates from NY springs — the OEM SP00350 is the standard 5 lb spring; the New York (NY1 / NY2) springs are heavier-pull alternatives (approximately 8 lb and 12 lb) designed for law enforcement agencies requiring double-action-like pull weights. If you want to restore stock feel after an NY spring installation, SP00350 is your part
