Redding 9mm Luger Full Length Sizing Die

The Redding 9mm Luger full length sizing die is the foundation of consistent, reliable handgun ammunition reloading. This die resizes the complete case—neck and body—to standard dimensions, ensuring proper chambering in your firearm and shot-to-shot consistency on the range or in competition. Whether you're loading range rounds or hunting ammunition, full length sizing restores cases to factory specs after firing, making it essential for any serious 9mm reloader.

Redding's full length sizing die includes a decapping assembly that removes spent primers in one operation, plus an expander ball to open the case mouth for bullet seating. The die works with standard single-stage and progressive reloading presses, giving you flexibility in your setup. For best results when installing your sizing die, we recommend using a headspace gauge to dial in the precise setup—this step ensures your loaded rounds chamber reliably and safely.

Full length sizing is the standard choice for shooters who want maximum compatibility and performance across different firearms, or who prioritize ease of loading over maximum case life. It's the logical starting point for new reloaders and a trusted workhorse in established loading benches across the country.
