The Hellcat is fantastic from the factory. It’s the highest capacity micro-compact on the market. However, any gun can be made better. These upgrades and accessories make it even better. Light and extended magazine options are here.

I made an effort to 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(source). 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.

Trijicon RMRcc

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

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

The battery requires removing the sight and re-zeroing. Trijicon says RMRs batteries last for more than 4 years of continuous use. You might want to replace the battery every 2 years to be on the safe side.

The dot is only available in red. There are 2 dot sizes available. I recommend the 3.25 MOA dot. In theory the larger the dot size the faster the eye alignment. I disagree with this logic. The RMRcc requires training regardless of the dot size and the small the dots size the more precise the shots.

It’s waterproof up to 20 meters. This makes it fully rainproof.

Using the RMRcc does not turn a Hellcat 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.

Trijicon gives a 5 year warranty from the date of manufacture.

3M WorkTunes Connect Hearing Protector with Bluetooth

This is my favorite set of hearing protection. I bluetooth it to my phone and listen to music when I am shooting. The headband and ear cups are comfortable. I can wear this all day. The battery lasts several hours. It recharges with USB.

The NRR(Noise Reduction Rating) is 24. That’s a bit low for shooting. It’s best to use ear plugs and these ear muffs together for maximum hearing protection.

Tritium Night Sights by Night Fision

Strangely, only the front sight is illuminated on the current Hellcats. As an owner of two handguns with both front and rear night sights, I find this odd and found a solution.

Night Fision claims to make the brightest tritium sights. Reviewers on the company website agree.

They are made in the USA with a limited lifetime warranty. The yellow and green tritium vials are warrantied for 16 years. Every other color is guaranteed for 5 years.

The rear sight will not fit the OSP version.

Talon Tactical 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 for 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.

Osprey 45 Suppressor

The Hellcat is great little gun 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 with a piston change.

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.

Of course a suppressor does not increase the stopping power of a pistol. Concealed carrying a pistol is large, uncomfortable combo. If you do carry a suppressed pistol, then you are straight savage.
