The Q Erect9R 9mm modular suppressor is a configurable 9mm can from Q (brand part no. SIL-E-9). Its modular design lets you run it in a shorter, lighter configuration or a longer one with more volume, so a single suppressor can serve several 9mm hosts. That makes it a practical choice for a shooter who wants one can for range days, training and a compact setup. The Erect9R carries Q’s direct, no-nonsense approach to suppressor design into the 9mm class.

Key Specifications

• The caliber is 9mm, the most common pistol and pistol-caliber carbine cartridge.
• The design is modular, so the suppressor can be configured shorter or longer.
