Warnings & Information

Keep out of reach of children

Installation requires specific technical skill or the work of an experienced technician; proceed carefully to ensure correct assembly and mechanical verification before use

Store components in a dry, moderate environment until installation, protecting springs and metal parts from dust and humidity

After installation, perform dry-fire tests with an empty slide to confirm proper hammer block and full reset before using gas and ammunition

Do not tamper with or modify OEM parts: any alteration voids mechanism safety, breaches GPSR compliance and Italian regulations, and undermines reliability and lifespan

If malfunctions or unusual behavior occur after installation, disassemble the trigger group, inspect each component, replace any defective or worn parts, and seek qualified service if needed

No minimum age is required to purchase internal spare parts, but installation demands appropriate expertise

Dispose of defective or worn components in compliance with applicable regulations for metal and mechanical waste
