Running a Strike Modular Chassis with a 3.9" SIG P320 slide and barrel? This is the piece that makes that setup work. The Alpha Comp mounts directly to the SMC Alpha MKII frame with a single thumbscrew, so you skip the threaded barrel entirely and keep your build simple. It's the large of the two size options, with more mass and a longer body than the small comp, which means a bit more surface area working to settle the gun back down between shots.
The whole point here is control. The comp mitigates felt recoil and knocks down muzzle rise, which translates to faster, flatter follow-up shots at the range or on the clock. Strike went with a widened bore on this design, and that's not just spec-sheet talk. The wider bore is there to help you avoid baffle strikes and keyholing rounds, which is exactly the kind of headache you don't want with a direct-mount comp riding that close to the muzzle.
This one is machined from S45C steel and finished with a Quench Polish Quench (QPQ) process, so it's built to take heat and hold up to regular shooting. Installation is about as painless as it gets. There's no permanent modification to your pistol, and the single thumbscrew means you can pull it or swap it whenever you like. One tip worth passing along from folks who run these: put a good threadlocker on the hardware and check it periodically, since direct-mount comps see a lot of vibration and you want it staying put.
Fitment is specific, so it's worth being clear. This is made for the Standard length Strike Modular Chassis Alpha setup running a 3.9" P320 slide and barrel. It is not built for 4.7" or 3.6" slides on the standard chassis, and it doesn't play with threaded P320 barrels. If your chassis and slide match up, this large comp is the direct answer.
It's built for the Standard length Strike Modular Chassis Alpha running a 3.9" SIG P320 slide and barrel. The comp direct-mounts to the chassis frame, so you don't need a threaded barrel. It is not compatible with 4.7" or 3.6" slides on the standard chassis or with threaded P320 barrels.
No. The whole design mounts directly to the chassis, which eliminates the need for a threaded barrel entirely. That saves you the cost and hassle of picking up a separate threaded barrel and keeps the build cleaner.
Installation is quick and requires no permanent modification to your pistol. A single thumbscrew holds it on, so you can install or remove it easily. It's smart to run a threadlocker on the hardware and check it periodically, since direct-mount comps take a lot of vibration during shooting.
The large comp has more mass and a longer body than the small version, which gives it a bit more to work with in settling the gun. It also sticks out further past the dust cover due to that added length. Both use the same direct-mount design and target recoil and muzzle rise on a 3.9" P320 SMC setup.
