8 Sig P320 Upgrades and Accessories


These are 8 upgrades that provide that improve on the factory Sig P320. Light and extended magazine options are here.

I made an effort rank these upgrades in order of importance.

Streamlight  TLR-2 HL G and TLR-4 G

You can hit what you can’t see. These Streamlight light and laser combos are excellent additions to any pistol with a rail. I recommend green lasers over red lasers. According to the NRA, green lasers are more visible in bright sunlight. Some folks don’t like running lights because the light is a target. I strongly disagree with this logic. It’s worth giving that slight advantage to an enemy to see clearly who the bullets are going to hit.

These two lights are superb. They each have 3 modes: light only, laser only, and laser and light together. The on/off switch is ambidextrous. Using your shooting finger, the switch on both sides turns these lights on or off.

The TLR-2 HL throws most of it’s lumens through the center beam for long distance illumination. Around the center beam, a wide disbursed shot of light provides illumination for close distances. This makes the TLR-2 HL a light for many applications. The TLR-4 provides plenty of light for close distances applications including room clearing and urban self-defense.

These lights have a limited lifetime warranty which excludes batteries, bulbs, abuse and normal wear. Rechargeable batteries, chargers, switch, and electronics are warrantied at for 2 years.

Apex Tactical Flat-Faced Action Enhancement Trigger Kit

Sig 320 Apex Trigger

Apex made a dope trigger upgrade for the P320. Trigger travel is reduces by 40%. The reset and pull weight are reduced by 20%.

In the X-Series modes, the pull weight increases 6% according to the Apex. I guess that is a 6% increase over the factory pull weight. The travel is reduced 30% in X-Series models.

It only works with Upgraded P320s.

This trigger kit will not work with a manual safety installed.

+5 Magazine Extension by Taran Tactical Innovations

This aluminum magazine extension adds 5 rounds to 9mm and 40 caliber P320 magazines.

It comes in 9 colers: black, flat black, blue, red, titanium blue, titanium grey, coyote bronze, od green, and titanium purple.

Trijicon RMR with Adjustable LED

Trijicon RMR with Adjustable LED

Tired of aligning the front and rear sights? Trijicon’s RMR will solve this problem for you. I am being a bit sarcastic, but getting on target is faster with a RMR.

The RMR comes with legendary Trijicon reliability. RMRs are trusted by police and militaries the world over.

The battery requires removing the sight and re-zeroing. Trij says RMRs batteries last for more than 4 years of continuous use. You might want to replace the battery every year to be on the safe side.

I recommend the adjustable LED RMR. This version gives shooters full control over dot brightness. The dot is only available in red. There are 3 dot sizes available. In theory the larger the dot size the faster the eye alignment. I disagree with this logic. The RMR requires training regardless of the dot size and the small the dots size the more precise the shots.

Using the RMR does not turn a P320 into a video game gun. You will still need to practice drawing the gun. It takes muscle memory to bring the dot to the eye every time.

Threaded Barrel by SilencerCo

I own two SilencerCo products and I have only good to say about this companies products. If you need a threaded barrel, this is good one.

It comes in the standard 1/2×28 threads. A protector is included.

It has a non-reflective black nitride finish.

There are barrels for the full-size and compact P320

PMM Sig P320 Compensator

This is an effective and reliable compensator for the P320. It screws on the popular 1/2×28 threading. A single port pointing up ejects the gas.

It will work with most factory loaded ammunition, but works best with +P and Nato Ammunition.

The colors available are black and flat dark earth.

Osprey 45 Suppressor

Concealed Carry Andrew's Osprey 45 Suppressor

The P320 is great and it’s even greater when shooting without ear protection.

Why did I choose the Osprey 45? It’s one of the quietest, I have one, and it has some great features.

The threads are on a removable piston. The allows the suppressor to fit on all common male thread sizes.

The unique tombstone shape makes the osprey sit lower than round suppressor when attached. This reduces the height a pistol’s sights need to rise above.

The Osprey 45 works with several common calibers including 45, 40, 10mm, 9mm, and subsonic 300 BLK.

Talon Tactical Grips

Sig P320 Talon Grips

Talon grips provide a large increase in traction over the factory grip texture. Granulated and rubber are the texture types. The granulated textures feels like sandpaper or skateboard tape. This texture is best with holster carry and competition shooting. The rubber texture is best for concealed carry because it will not irritate skin. Also shooters with soft skin should use the less abrasive rubber texture.

They are made in America with a 90 day warranty.

Andrew Jordan

I’m a lifelong native of Memphis, TN. Shooting drills especially with 22LR are one of my passions. My concealed carry permit application was submitted on my 21st birthday. The P10C is my EDC pistol. I invented the patented 15 round 5.56 stripper clip. You can also find me on the “Concealed Carry Andrew” Youtube channel.
