Rival Arms Firing Pin for GLOCK 9/40 GEN3/4 Twist Black

The Rival Arms Firing Pin for Glock 9/40 Gen3/4 Twist Black is a precision-engineered replacement striker designed to outperform factory Glock firing pins in durability, wear resistance, and long-term reliability. Built from billet stainless steel and finished with a proprietary PVD (Physical Vapor Deposition) coating, this component is engineered for high-volume shooters who demand consistent ignition performance across thousands of rounds.

The firing pin features tighter tolerances than OEM Glock strikers, reducing slop and improving shot-to-shot consistency. The low-temperature vacuum PVD coating creates a durable barrier that resists corrosion, wear, and the effects of repeated impact cycles. This self-lubricating surface reduces friction and extends service life, making it ideal for law enforcement, military, and competitive shooters who cycle thousands of rounds annually. The Twist profile geometry optimizes striker energy transfer for reliable primer ignition across all standard 9mm and .40 S&W ammunition.

This replacement firing pin is compatible with Glock Generation 3 and Generation 4 platforms chambered in 9mm and .40 S&W, excluding the G43, G43X, and G48 models. It addresses a common wear point in high-round-count Glocks where factory strikers develop surface degradation, potentially leading to light primer strikes or ignition delays. Agencies and serious shooters rely on upgraded strikers like this to maintain consistent ignition reliability and reduce the maintenance intervals on their duty or carry weapons.
