Griffin Armament CAM-LOK Barrel Adapter 1/2X28 Special for Sig P365 & Glock 43/43X/48 (PI1228S)

The Griffin Armament CAM-LOK Barrel Adapter brings fast, secure QD (quick-detach) suppressor mounting to compact pistols—specifically the Sig P365 and Glock 43/43X/48. If you're running a tilt-barrel pistol and tired of direct-thread suppressors that eat up your shooting time, the CAM-LOK interface is a game-changer. This 1/2×28 threaded adapter uses Griffin's patented universal QD piston system, giving you tool-free mounting and remounting without the fumbling of traditional setups.

The real innovation here is the geometry: the forward taper surface locks the piston firmly in place while minimizing baffle strike and eliminating most of the side concussion and visual disturbance you'd get with a blind-end design. The CAM-LOK's three mounting positions—spaced 120 degrees apart—let you spin the suppressor on and off rapidly while maintaining a rock-solid connection. Installation is straightforward with a 3/4-inch (19mm) wrench, and the coarse threads are cut to resist wear over thousands of cycles.

Built tough with a QPQ nitride finish that looks clean and handles corrosion, the CAM-LOK adapter weighs the same as legacy direct-thread piston systems but delivers a speed and security advantage that matters in the field. Compatible with Griffin's universal QD pistons (sold separately), so you can outfit multiple suppressors or swap across your compact pistol lineup without replacing the adapter.

Frequently Asked Questions

What pistols does the CAM-LOK Barrel Adapter fit?

This adapter is designed for the Sig P365 and Glock 43/43X/48—all tilt-barrel, compact pistols with 1/2×28 threaded barrels. Verify your barrel thread pitch before purchasing.

Do I need a piston, and is one included?

The adapter works with Griffin Armament's universal QD pistons, which are sold separately. The adapter itself is the threaded component that attaches to your barrel; the piston is the part inside your suppressor that mates with it.

How does CAM-LOK compare to direct-thread suppressors?

CAM-LOK is a quick-detach system that mounts and dismounts without tools in seconds. Direct-thread suppressors screw on hand-tight and take longer to install and remove. CAM-LOK also reduces baffle strike and side concussion through its forward taper design.

What wrench size do I need to install this adapter?

Use a 3/4-inch (19mm) wrench for installation and removal. A socket wrench is recommended for secure, easy operation.
