The HA Magwell Description 

A magwell is a very important accessory for your carry weapon. It is ideal for IDPA-style practical shooting competitions too. Your SIG P320 magwell will increase your reloading speed and help ensure you don't fumble during high-stress tactical reloads.

The Herrington Arms SIG P320 magwell has been constructed of light yet durable weapons grade 6061 aluminum. It won’t chip or break easily even if you drop your P320 pistol on a hard surface. It has been precision engineered on cutting-edge CNC machinery and designed to withstand the impact of even very high-speed reloads.

We noticed a flaw in the magwell's from our competitors, you could not use a flush fit standard capacity magazine. We see this as a problem as most of our customers conceal carry their coemption handguns. So, we resolved this problem by machining clearance notches in the magwell for an oem magazine baseplate. For EDC printing is a big concern and if you have to carry an extended mag in the gun you will almost always print. This magwell gives you the best of both worlds, with a funnel for reloads and the ability to carry the standard mags!

 

The HA Mag Extension Description 

With the Herrington Arms +5 SIG P320 magazine extension, there is no need to fear running dry in any situation where every shot counts.

This highly durable mag extension is made of light yet very strong weapon grade 6061 aluminum. It works well in all weather conditions and won’t break easily, even if dropped with a full magazine.

This mag extension has been precision engineered on state-of-the-art CNC machinery to consistently deliver the same outstanding quality, time after time-every time. It is available in FDE Cerakote and matt black anodized finish, and will add a touch of extra class to your P320 pistol.

Reliability

Every compensator we manufacture has undergone rigorous reliability testing!

The design phase

Every product we make goes through a week long design process and multiple versions before we machine a prototype!

CNC Machining

We currently machine all of our compensators on 2 brand new Doosan DNM4500S CNC milling machines and a 2019 Tormach 1000mx CNC milling machine!

FAQs

The answer is easy! All you need to do is purchase the threaded barrel that matches your slide. For example, if you have a carry length slide you need a carry length threaded barrel (4.6"). If you have an X compact slide you need a X compact threaded barrel (4.3"). This will allow you to run a longer frame and give you an integrated look.

320 COMP INTEGRATION VIDEO LINK

Yes they do. We have run tens of thousand of rounds through all of our models and have had zero malfunctions. If you are having an issue with a build, it is likely the case you have installed our prodcut incoretly or your handgun needs broken in. Compensators need a smooth running system to be reliable. A new handgun has tolerances that need to be worn in before we suggest adding a compensator

-It's easy! We designed our comps to be self-timing so all you have to do is

- Remove your slide from you frame

- Remove your guide rod assembly

- Apply Loctite to barrel threads

- Thread comp onto barrel until it stops

- Back off a 1/8 turn

- Apply Loctite to set screws

- Tighten down set screws
