The Herrington Arms HC3652P two port Compensator has been expressly created to fit and work with Sig Sauer's popular P365 series of handguns. 

Herrington Arms have specifically engineered it to prevent a common issue known as vertical climb. When you shoot your P365, it will flip upwards, and it will take you a second or two to re-align the sites to your target.

Why Should You Compensate Your Weapon? 

Compensators are practical accessories that enable your weapon to perform better than it ever did before. A properly compensated handgun won't 'jump' as much in your hand as a non-compensated one.

You will be able to re-acquire and engage your target faster, and you will become a much more accurate shooter.  This has a lot to do with how your body perceives felt recoil.

The laws of physics being what they are, it is not possible to eliminate recoil. However ‘felt recoil’ can be directed away from the body. This is what a compensator does very well. It has been equipped with porting holes on top. When you discharge your firearm, the propellant and its hot gases propel the projectile towards your target. Since the Sig P365 operates based on the time-tested locked breech, tilt barrel mechanism, its barrel also tilts upwards.

The HC3652P Compensator

Here, your HC365 Compensator truly comes into its own. Its ports have been meticulously designed to enable the gases to escape upwards. This will push the weapon downwards, even as its mechanism tilts it upwards. The two forces cancel each other out. The result is an extremely stable weapon.  It is also a great way to enjoy a day at the range without any fear of flinching.

Flinching occurs when the body anticipates recoil and shies away from it by flinching or jerking the hand backward. This spoils the shooter's aim and creates a bad habit that is very difficult to overcome. In time, flinching caused by excessive muzzle climb takes the joy away from shooting sports. However, your Herrington Arms HC3652P Compensator will take care of this issue permanently.

It works perfectly well with stock springs so you won’t need to change anything on your carry weapon. The HC3652P will easily fit on all 1/2-28 threaded barrels for the P365X, P365XL, and P365 model pistols.

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!


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.


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

Amazing compensator

This is the second comp I have purchased from Herrington arms (p320,365)and absolutely love them both but would like it if they included extra set screws as there small and strip easily do yourself a favor and add a few to your cart when you make you purchase

So far so good.

I installed this compensator (incredibly easy) and have put 100 rounds so far through it. Had no malfunctions and definitely brings down the recoil.

HC Comp

Good quality machining, very easy to mount and tighten down. It is not a night and day different but it definetly does reduce recoil and muzzle rise. Over great product

Comp works great, you do have to be careful and not use under powered ammunition. I have found that anything less than 1150 fps for muzzle velocity makes the brass ejection not as pronounced, most defensive ammo go 1180 fps and up so that should be just fine. Oh used on stock springs.
