Griffin GA9QDK | 3-Lug 9mm Coupler Kit

The Griffin Armament GA9QDK 3-lug coupler kit provides a minimal-length 3-lug interface that enables quick-detach mounting for a variety of pistol suppressors. It is designed to fit H&K standard 9mm 3-lug adapters as well as Griffin 3-lug adapters and is intended to preserve compact overall length when used with compatible suppressors. The kit is offered with 17-4 stainless steel construction and a black finish as described in the product data.

Typical uses include range and target shooting where a QD suppressor interface speeds attachment and removal, and competition applications where repeatable, low-profile mount geometry is desirable. The adapter requires minimal spring bushing deflection for installation in many setups, which can reduce or eliminate modifications to hand stops and closely fitted grips.
