The difference between the HC320 and HC320XL

The HC320XL is 1/8" longer than the HC320 and only has dual top ports instead of our flagship side and top ports. Both comps reduce recoil at almost identical percentages but the felt recoil in your hand feels slightly different. The HC320 has a softer felt recoil in the hand but the HC320XL has a little less muzzle flip. We designed the HC320XL specifically for the guys running the Flux Defense Raider Chassis (FLUX RAIDER (Brace) — FLUX Defense) and guys who shoot a lot from retention. It honestly comes down to personal preference on which comp is the comp for you!

The P320 X Full & HC320 Compensator

The new P320 X FULL rounds out the X Series with an entry full-size model.   The 4.7” slide and 5.5" threaded barrel offer unparalleled accuracy and comfort without sacrificing the ability to carry concealed.  The grip module is compatible with the removable magwell and grip weight and is designed with an extended beavertail and deep undercut for a high grip and better recoil control.  The XRay3 day/night sights offer high visibility in all lighting conditions, and the rear sight plate assembly allows the direct mounting of the new Romeo1 PRO optic, as well as the popular Delta Point Pro.  The new LCI flag allows visual and tactile confirmation of a loaded chamber with ease.  Each P320 X FULL comes standard with two (2) 17rd mags.

The HC320 Compensator adds its powerful recoil reducing properties to your P320X full-size pistol with flawless fit and comes in FDE Cerakote or Black Anodized options, it’s a smart upgrade if you need to evolve your pistol’s target re-acquisition abilities after each bullet.

The P320 X Carry & HC320 Compensator

Now, all of these features are available in the most comfortable size. The P320 X Carry features a full length grip, a shortened dust cover and a low-profile internal magwell. Combined with the extended beavertail and high undercut trigger guard, the X Carry offers ultimate comfort and concealability AND improved recoil control. The 4.6" threaded barrel and 3.9” X series slide with enhanced serrations come equipped with the X-Ray3 day/night front sight with rear night sight plate assembly. The X Carry is fully compatible with the new ROMEO1 PRO reflex optic as well as the popular Delta Point Pro and comes with two (2) 15-rd magazines.

About Sig Sauer

In 1853, Friedrich Peyer im Hof, Heinrich Moser and Conrad Neher began what they thought would become a successful wagon factory above the Rhine Falls in Switzerland.

Little did they know then, their company would become one of the world’s most renowned manufacturers of small arms. Just seven years after constructing an industrial plant for building the most sophisticated wagons and railway cars, the three ambitious owners undertook a more serious venture.

In part to a challenge from Switzerland’s Federal Ministry of Defense, the Swiss Wagon Factory entered the competition to develop a state-of-the-art rifle with the hopes the Swiss Army would adopt it.

At this point, the Swiss Wagon Factory, with an order for 30,000 muzzle loading Prelaz-Burnand rifles in hand, changed the name of the company to the Swiss Industrial Company – Schweizerische Industrie-Gesellschaft, known worldwide as SIG.

Fast-forward to the 20th century, in 1949, the SIG P49, the forerunner of the SIG P210 was developed for the Swiss Army and destined to become a legend on the battlefield as well as the competition field. That same year, the P220 made its appearance as the new pistol for the army, soon followed by the compact P230 for the Swiss Police. These pistols offered new features and levels of reliability never before seen in the industry.

October 1, 2007 SIGARMS changed its name to SIG SAUER.

The change reflected the vast worldwide growth in demand for Sig Sauer products. In response, the company more than tripled its work force in the next 30 months, invested 18 million US dollars in state-of-the-art manufacturing facilities and equipment, and significantly expanded its engineering base. The name change, coupled with major new product introductions in pistol and rifles, reflects the continued commitment to the high standards of production, service and innovation the Sig Sauer brand has always represented.

The Herrington Arms HC320 Compensator is an amazing compensator that greatly reduces the vertical and horizontal recoil of your P320 with two finish options of FDE or Black to match your weapon color. This is easily one of the best upgrades for your P320 platform that is also at an incredibly competitive price point.

    HC320

    Posted by Ryan Bollinger on Jun 19th 2025

    I was shocked how easy it was to install this comp, I will be purchasing more next week. Noticeably less muzzle rise and gun cycled with stock spring.

    It’s ok to “Compensate”

    Posted by Bryan Childers on Jun 19th 2025

    It was easy to install, and works perfectly! It definitely makes each shot softer feeling and helps to stay right on target with nearly zero muzzle rise. I shot 5 different loads, to see if I would have any cycling issues, but was pleased that all worked perfectly! This was a great purchase. Look forward to a lot more range time. Bryan from NC

    HC320 Comp

    Posted by Shawn Prescher on Jun 19th 2025

    I ordered the HC320 comp from Herrington Website. Item was on backorder but was not delayed. I attempted to install the comp after it arrived and was too tight to fully install. I reached out to Herrington and was contacted immediately by Cory. He emailed me a return label for the defective comp and sent out the replacement the same day. It arrived in two days and was a perfect fit. Love it and great customer service. Thanks Herrington!

    Solid product.

    Posted by Sam K on Jun 19th 2025

    My set up is a p320 xcarry Legion. Overall satisfied with the performance of the product. I purchased an AC compensator to compare and on the stock recoil spring the Herrington Arms compensator performed better. With the AC comp I was having stove piping almost every shot. The Herrington Arms comp still had some cycling issues. After about 200-300 rounds I had 15-20 stove pipes. I'll look to pair it with a DPM recoil spring to get it cycling flawlessly.

    Fantastic product

    Posted by Thomas Zmudosky on Jun 19th 2025

    The P320 is already a smooth running firearm. This comp paired with 124gr. ammo reduces a noticeable amout of recoil. I will be purchasing another HA comp for my other 320 and glock.
