This Springfield Armory Hellcat Pro OSP is an exceptionally complete, thoughtfully upgraded 9mm package that combines the slim, high-capacity proportions of the Hellcat Pro with a premium threaded-barrel and compensator arrangement, an electronic sight, a rechargeable weapon light and an unusually generous complement of magazines and supporting equipment. The pistol is presented in excellent used condition with an excellent bore. Its optics-ready slide is fitted with a Crimson Trace CTS-1500 micro reflex sight featuring a highly visible 5-MOA red aiming dot. A compact Olight PL-Mini 2 Valkyrie rechargeable weapon light is mounted to the accessory rail, providing a clean, compact illumination solution that complements the Hellcat Pro's concealed-carry dimensions. The factory barrel has been replaced with a True Precision threaded barrel and paired with a Herrington Arms HCAT compensator. This carefully selected combination gives the pistol a distinctive performance-oriented appearance while retaining the original Springfield barrel for buyers who prefer the factory configuration. The original barrel is included with the sale, making the package substantially more versatile than a permanently altered pistol. Included are three 15-round magazines and two extended 17-round magazines, providing a total of five magazines suitable for carry, training and range use. The package also includes the original Springfield Armory box, factory soft case, larger Springfield range bag, original paperwork and packaging, together with a custom Kydex holster configured around the pistol's mounted accessories. The photographs show a remarkably clean pistol with only minor evidence of normal handling and operation. The slide, frame, controls and exterior metal surfaces remain attractive, with no obvious major damage or corrosion visible. Normal contact markings may be present on the barrel, magazines and other moving or removable components. This is a compelling opportunity for the buyer seeking a Hellcat Pro that is already equipped with a threaded True Precision barrel, Herrington Arms compensator, Crimson Trace optic, rechargeable Olight weapon light, five-magazine complement and compatible custom holster, while still retaining the original barrel and Springfield packaging. This is a used firearm and may display minor handling marks, finish wear or other cosmetic imperfections consistent with previous ownership and operation. Please review all photographs carefully, as they form an important part of the description. Accessories, optic zero, and battery condition should be confirmed by the purchaser before defensive use. All used firearms are sold as is, with no warranties, expressed or implied.
