Hellcat Pro OSP vs. Hellcat Micro Compact

Many in the gun community are already familiar with Springfield Armory’s Hellcat Micro Compact. The award-winning handgun was released in 2019 and quickly became one of the top concealed carry guns for its many impressive features packed into such a small frame.

And just when we thought it couldn’t get any better, Springfield Armory released the Hellcat Pro OSP in March 2022. The Pro model is designed with all the same features that made the Micro Compact so popular, with a few additional upgrades.

You really can’t go wrong with a Hellcat. But with the release of the new Pro model, we figured to create a side-by-side comparison of the Hellcat Pro OSP vs. Hellcat Micro Compact so you can easily see the differences between the two.

Now enough blabbing. Let’s get into it.

Hellcat Micro Compact

Hellcat Micro Compact

Known as the highest-capacity micro-compact pistol on the market today, the 9mm Hellcat Micro weighs only 18.3 oz. unloaded, yet can hold an impressive 11 rounds. It can also hold up to 13 rounds with an extended magazine.

The original Hellcat was specifically designed for everyday carry, sporting high visibility sights, and Adaptive Grip Texture. It’s known for its extreme durability and reliability and is available in an optics-ready model.

The Hellcat Micro Compact has a barrel length of 3” and an overall height of 4”. It has a black polymer frame and a dual captive recoil spring with a full-length guide rod.

Hellcat Pro OSP

Hellcat Pro Osp

The Hellcat Pro OSP is similar to the Micro Compact in many ways yet has a few of its own unique qualities. The main difference is their size; the Pro model now comes with a longer grip and a longer hammer-forged barrel.

The Pro has a barrel length of 3.7” and a height of 4.8”. The Hellcat Pro OSP weighs 21 oz. and comes standard with a flush 15-round magazine, offering a larger capacity than any other gun in its size.

The optics-ready 9mm Pro is built with a black polymer frame and an Adaptive Grip Texture as well. Also similar to the original Hellcat, the Pro has a dual captive recoil spring with a full-length guide rod.

Specifications of the Hellcat Pro OSP vs. Hellcat Micro Compact

Barrel Length
21 oz
17.9 oz
11 +1 (13 +1 w/ extension)


Both Hellcats have the largest magazine capacity for their size of any gun on the market, something Springfield Armory takes a lot of pride in.

The Hellcat Micro Compact comes standard with a flush 11-round magazine, an impressive capacity for a pistol weighing only 17.9 oz. An extended magazine is also available for the Compact, increasing the gun’s capacity to 13 + 1. The extension does increase the pistol’s weight to 18.3 oz. and adds half an inch to the gun’s overall height.

The Hellcat Pro weighs in at just 3.1 oz. more than the Micro Compact, but its larger 15-round flush magazine makes it worth it if you’re more interested in capacity than weight (is 3 oz really a dealbreaker anyway?).


Hellcat Pro and Holster

Frame: Both Hellcat models have the same black polymer frame with a custom pressure Activated Grip Texture. Their slim-line grips feature a pattern of staggered pyramid shapes. The taller pyramids in the pattern are designed with flattened tops to make the pistol more comfortable in your waistband and reduce wear on clothes. The shorter pyramids come to a point so the gun effectively locks into your hand when it's firmly gripped.

The only difference in the two frames is their size. The Hellcat Pro’s grip is a bit longer than the original, allowing for a more comfortable grasp and increased hand contact and control, making it a great option for anyone who found the original Hellcat to be a little too small for their hands.

Slide: Both Hellcats feature top, rear, and front slide serrations making it easier to quickly rack the slide. Similarly, the slide on both guns is billet machined with the Springfield Micro footprint, making them compatible with the smallest and most popular micro red dots available.

Barrel: The Hellcat Pro’s barrel is slightly longer than the original Hellcat’s, measuring 3.7” and 3” respectively. Their barrels are made from hammer-forged steel and are finished with a protective Melonite coating.

The one barrel difference in the Hellcat Pro OSP vs. Hellcat Micro Compact is the additional weight and mass in the Pro’s barrel, which is designed to allow for a reduced muzzle flip and faster follow-up shots.


Both the original and Pro Hellcat models come with the same high-visibility tritium and luminescent front sight along with a Tactical Rack U-Dot™ rear sight. Springfield Armory’s U-Dot is designed with luminescent green rings around the tritium dot, giving the shooter large, visible sights for aiming in low-light conditions.


With the Hellcat Micro Compact, you can choose whether you want your pistol to come optics ready or not. Alternatively, all Hellcat Pros come optics ready. Both guns are designed to be compatible with red dot sights, and the Springfield Micro footprint milled into the slide allows you to use even the smallest red dot sights on the market, including the HEX™ Wasp, JP Enterprises JPoint™, and Shield RMSc.

The Hellcat Pro OSP’s extended, versatile Picatinny rail is larger than the original, so it can be used with many systems that were too big for the original Hellcat model.

Trigger: The original Hellcat was built with Springfield Armory’s Gen 2 trigger, allowing for a comfortable shooting experience, while the Hellcat Pro comes with the Armory’s new Gen 3 trigger, which is a flatter and firmer trigger.

Safety: While the Hellcat Micro Compact is available either with or without a manual safety, the Pro model is not manufactured with any sort of external safety, though it does feature a trigger safety, a striker pin safety, and, like the Micro, a loaded chamber indicator.
