Description
The Hellcat OSP launched in 2019 and immediately flipped the script on what people expected from a micro-compact carry pistol. At only 6 inches overall and a grip width of exactly 1 inch, it disappears under a t-shirt while still putting 11+1 rounds in your hand with the flush magazine and 13+1 when you drop in the included extended mag. That kind of capacity in that size of package was genuinely unheard of when this gun hit the market, and it still holds its own in a crowded field.
The OSP part of the name stands for Optical Sight Pistol. The rear of the billet-machined slide has a factory-cut optics deck with a removable cover plate, compatible with popular micro red dot footprints like the Shield RMSc and JP Enterprises JPoint. Drop a dot on it or leave the plate in place and run iron sights. Either way, the gun comes ready to work out of the box with Springfield's tritium and luminescent U-Dot front sight paired with a Tactical Rack U-notch rear. That front sight is bright, fast, and visible whether you're in a dim parking garage or full daylight.
The barrel is a 3-inch hammer-forged steel unit with a Melonite finish and a 1:10 twist rate. The same Melonite coating covers the slide, giving both components solid corrosion resistance and long-term durability. The frame is black polymer with Springfield's Adaptive Grip Texture, which uses a pattern of staggered pyramids designed to grip harder the more pressure you apply. For carry comfort, the taller peaks are flattened so the texture stays skin-friendly against the body. The flat-faced trigger uses a nickel boron-coated group underneath, and the mag release is reversible at the user level. There's also a standard accessory rail on the dust cover for a compact light or laser, a loaded chamber indicator, and front and rear slide serrations including the top-of-slide serrations for positive racking in awkward positions.
Two magazines ship in the box: one 11-round flush-fit mag and one 13-round extended. The Hellcat has been around long enough that holster support, aftermarket triggers, sights, mag extensions, and weapon lights made specifically for this platform are widely available from dozens of manufacturers.

Frequently Asked Questions
What micro red dots are compatible with the Hellcat OSP slide cut?
The Hellcat OSP slide is cut to accept micro red dots using the Shield RMSc footprint, which covers a wide range of popular options including the Shield RMSc, Springfield's own HEX Wasp, and the JP Enterprises JPoint. The cover plate removes easily with two screws, and many red dot manufacturers include the correct mounting hardware in the box. It is always worth confirming your specific optic's compatibility before purchasing.
Does the Hellcat OSP come with night sights?
Yes. The Hellcat OSP ships with Springfield's U-Dot sight system, which features a tritium vial surrounded by a luminescent ring on the front sight for visibility in low-light conditions. The rear is a drift-adjustable Tactical Rack U-notch design. The combination gives you a fast, high-contrast sight picture whether you're running iron sights alone or co-witnessing with an optic.
Is the Hellcat OSP a good choice for appendix carry (AIWB)?
It is one of the more popular pistols for appendix carry, largely because of the slim 1-inch grip width and the relatively light unloaded weight of around 18 ounces. The grip texture is designed to be comfortable against the body during all-day carry without being abrasive. Holster options for the Hellcat OSP from brands like Crossbreed, Crucial Concealment, Vedder, and CYA are widely available and well-established.
What is the difference between the standard Hellcat and the Hellcat OSP?
The only hardware difference between the two is the milled optics deck on the OSP's slide. Both models share the same frame, barrel, trigger, sights, and magazine compatibility. The OSP ships with a flush cover plate installed over the optic cut, so it runs like a standard pistol until you decide to mount a red dot. Given how widely available micro red dots have become for carry use, the OSP is generally the more versatile long-term choice.
How much does the Hellcat OSP weigh when fully loaded?
Unloaded, the Hellcat OSP weighs approximately 18.3 ounces. Loaded with the 11-round flush magazine plus one in the chamber, it comes in around 22 ounces, which is well within the comfort range for most carry setups. For reference, that loaded weight is comparable to many single-stack carry guns despite the Hellcat carrying significantly more rounds.
Is there a good aftermarket for the Springfield Hellcat?
The Hellcat has been on the market since 2019 and has built up a substantial aftermarket ecosystem. Holsters are available from virtually every major manufacturer, and there are Hellcat-specific options for triggers, sights, magazine extensions, weapon lights, and slides. The OSP configuration is particularly well-served since the optic footprint is a common one, making red dot selection straightforward.
