Springfield Armory is releasing the new Hellcat Pro OSP with Threaded Barrel, which features an extended 4.4-inch-long threaded barrel ready to accept the suppressor or muzzle device of your choice.

The Hellcat Pro is a compact pistol chambered in 9mm that offers 15+1 round capacity in a smaller footprint compared to similar guns in its class. The compact 9mm packs this larger capacity yet still maintains the ergonomic and slim profile of the original Hellcat pistol, allowing for seamless concealability.

“The Hellcat Pro OSP has proven itself to be a highly capable CCW pistol that combines full-size pistol performance with concealable dimensions,” says Steve Kramer, Springfield Armory’s Vice President of Marketing. “With the addition of a 4.4-inch, threaded barrel, this new Hellcat Pro OSP offers a whole new dimension of capability to this proven platform.”

The barrel of this new Hellcat Pro OSP, like the original Hellcat and Hellcat Pro, is made from hammer-forged steel with a black Melonite finish. The barrel has a 1:10-inch rate of twist, and has 1/2x28 tpi threading that makes it compatible with a wide range of suppressors and muzzle devices.

The "OSP" in the name of this new pistol stands for “Optical Sight Pistol”, which means the Hellcat Pro OSP with Threaded Barrel has a slide that is milled to accept dots compatible with the Springfield Micro footprint. The slide is designed to direct mount the smallest, most popular micro red dots on the market for the lowest mount possible. There is an  set of co-witnessing U-Dot sights that are made up of a high visibility tritium & luminescent front sight paired with a rear sight that has a notch for easy one-handed slide manipulations. The pistol also ships with two 15-round magazines.

The pistol also features a short length of Picatinny rail on the dustcover portion of the frame, which provides users the flexibility to deploy a wide range of accessories such as lights or other gear for use in a variety of applications and conditions.

MSRP for the Hellcat Pro OSP with Threaded Barrel is $667. For more information on this pistol or other products from Springfield Armory, please visit
