The Springfield Armory Hellcat Pro 9mm Luger semi-automatic pistol, freshly introduced by Springfield Armory on the US market and manufactured in Croatia by HS Produkt, is a larger variant of the Hellcat micro-compact, a concealed carry-oriented handgun first launched in 2019.

Just like the Hellcat micro-compact, Springfield Armory's new Hellcat Pro is a polymer frame, single-action, striker-fired pistol, featuring a reversible magazine release catch but no manual safety – a set of automatic trigger and striker safeties taking its place.

Whilst the Hellcat micro-compact was more or less exclusively conceived as a concealed carry handgun, the new Hellcat Pro will fare well both as a concealed and open carry option, for both civilians and professionals – chiefly law enforcement and private security.

Standing at 16,7 centimeters (6.6") in overall length, the new Springfield Armory Hellcat Pro pistol features a 9,3 cm / 3.7" barrel and weighs in at barely 595 grams (21 oz) when empty.

The slightly larger size makes the Hellcat Pro easier and more comfortable to handle even by larger-handed shooters, and easier to shoot. The 3.7" barrel offers improved ballistics over the shorter barrel of the Hellcat micro-compact.

What makes the Springfield Armory Hellcat Pro extremely comfortable and effortless to carry, both open and concealed with minimal printing, is the extremely low width – barely 2,54 cm / 1" at its wider point at the grip – despite the fact that the double-stack, flush-fit, metal magazines with polymer floorplate and elevator host a staggering 15 rounds of ammunition (staggering for the size and width, that is).

An additional round may be held in chamber, and higher-capacity magazines may be released in the future, by either Springfield Armory itself or third-party suppliers.

The barrel of the Springfield Armory Hellcat Pro pistol is cold-hammer forged out of high-grade steel, features a 6 grooves, right-handed rifling with a 1:10" twist rate, and is protected by a black thermo-chemical ferritic nitrocarburized surface treatment (Melonite).

The slide of the Springfield Armory Hellcat Pro is likewise manufactured out of stainless steel, machined out of solid billet, Melonite-treated in matte black for additional resistance against wear and tear as well as against corrosion and external aggressive elements, and offers features such as front and rear slide serrations; a loaded chamber indicator, in the form of a small hole just behind the ejection window that makes the status of the firearm readily discernable both visually and by feel; and a protected machined interface on top of the slide, allowing the use of micro red dot sights – an increasingly sought-after feature on service and defensive pistols.

Dubbed the OSP (Optical Sight Pistol), Springfield Armory's interface allows the use of a vast majority of popular and common micro red dot sights, including some of the top products from the best known manufacturers in the industry.
