Springfield Hellcat OSP 9mm 3″ 10-Round Black
About this product
The Springfield Hellcat OSP is a micro-compact, optics-ready 9mm pistol designed for concealed carry. It uses a 3-inch hammer-forged steel barrel and accepts micro red dots on the SHIELD/RMSc footprint. This configuration allows for a 10-round capacity in a package weighing 17.9 ounces unloaded, making it a serious option for daily defensive use.
What is the Springfield Hellcat OSP used for?
The Springfield Hellcat OSP is primarily used for concealed carry and personal defense. Its 3-inch barrel and slim polymer frame allow for deep concealment in an appendix or inside-the-waistband holster, while the 9mm Luger chambering provides legitimate stopping power. The optic-ready slide also makes it viable for low-profile competition or as a designated home-defense weapon when paired with a weapon light.
How does the Springfield Hellcat OSP compare to the Sig Sauer P365?
The Springfield Hellcat OSP offers a more aggressive grip texture and a slightly shorter overall height than the Sig Sauer P365. While both pistols have nearly identical barrel lengths (3.1 inches for the P365 vs. 3 inches for the Hellcat) and capacities in their base configurations, the Hellcat's slide serrations are deeper and its factory sights include a tritium front for faster low-light acquisition. The P365 generally has a smoother trigger pull out of the box, but the Hellcat's grip provides better control during rapid strings of fire.
What does it weigh and what are the dimensions?
The Hellcat OSP weighs 17.9 ounces (508 grams) without a magazine or optics plate installed. Its overall height is 4 inches, its length is 6 inches, and its width is 1 inch across the slide. This compact size, especially the 4-inch height, is critical for concealment and is why it beats many bulkier home-defense options like our Stevens 334 rifle for discreet carry.
Who is this NOT for?
This pistol is not for new shooters seeking a gentle training platform or for those prioritizing pure competition accuracy. The 3-inch barrel generates noticeable muzzle flip and a snappy recoil impulse that can be challenging for inexperienced users, unlike the softer-shooting, longer-barreled options. It's also ill-suited for handloaders chasing extreme velocity, as the short barrel sacrifices significant powder burn efficiency compared to a full-size duty gun.
What's in the box?
The box contains the Hellcat OSP pistol, two 10-round single-stack magazines, a polymer optic mounting plate for the SHIELD/RMSc footprint, a cable lock, and all Springfield factory documentation. You do not get a holster, a weapon light, or suppressor-height sights—those are add-ons you must procure separately if you plan to use a threaded barrel or suppressor, which I detail in my guide on Title II/NFA configurations.
Is the Springfield Hellcat OSP worth it at $589.99?
At $589.99, the Springfield Hellcat OSP is worth it for the shooter who demands an optics-ready micro-compact right out of the box. This price includes the optic cut and tritium front sight where competitors often charge $100-$150 extra for that configuration. If you do not intend to mount a red dot, you are paying for a feature you won't use, and a standard Hellcat model at around $500 would be a better value.

Frequently asked questions
- Is it compatible with Holosun optics?
- Yes, it is directly compatible with the Holosun 407K and 507K models, which use the SHIELD RMS footprint. No adapter plate is needed—remove the provided polymer cover and mount the optic directly to the slide's machined recess. Installation requires applying 15-17 inch-pounds of torque to the mounting screws.
- Does it fit a Tier 1 Concealed Axis Elite holster?
- Yes, the Hellcat OSP fits most holsters molded for the standard Hellcat, including the Tier 1 Concealed Axis Elite. Since the OSP model's slide is only 0.1 inches taller to accommodate the optic cut, it does not affect holster compatibility with Kydex or polymer designs. Leather holsters may require a break-in period of about 50 draws.
- How long does shipping take to an FFL?
- Processing and shipping to your chosen FFL dealer typically takes 3-5 business days after payment clears. All firearms shipments from Ironclad Armory use UPS or FedEx with adult signature required. You will receive a tracking number within 24 hours of the package leaving our warehouse.
- Can I return it if it fails to cycle my ammunition?
- We accept returns for mechanical defects within 30 days of delivery, but ammunition-related cycling issues are not grounds for return unless the firearm fails with three different factory loads from reputable brands like Federal, Speer, or Winchester. Most feed issues with the Hellcat are resolved with a 200-round break-in period using 124-grain NATO-spec ammunition.
