The Springfield Hellcat OSP is a compact semi-automatic 9mm pistol with a 3-inch stainless steel slide over a black polymer frame. It weighs 18.3 oz unloaded, measures 6 inches overall, and ships with two 10-round magazines. The OSP designation means the slide is cut for optics from the factory.

Detailed Features 

The optics-ready slide lets you mount a red dot without machining. Standard iron sights are included, so the gun works out of the box whether or not you add an optic. The textured polymer grip holds well in wet or sweaty conditions. 
 
At 18.3 oz unloaded, the Hellcat OSP is toward the lighter end for a 9mm, which matters over a full day of carry. The integrated trigger safety is the primary passive safety. There is no external thumb safety on this model. 
 
The 10-round flush magazine is sized for deep concealment; Springfield also offers extended magazines for range use. 
 

Usage 

The Hellcat OSP is set up for concealed carry and home defense. The 3-inch barrel and compact grip keep the profile minimal for IWB carry, and 10+1 of 9mm is a practical round count for a micro-compact. The optics cut is useful for anyone who wants a red dot without sending the slide out for work. Just mount and go.

Owners of the Springfield Hellcat OSP generally rate it well for its intended use as a concealed carry pistol, with a few recurring concerns.

The compact size is the main draw. Owners who carry daily find the 6-inch overall length and 18.3 oz weight easy to manage in an IWB holster without printing. The optics-ready feature gets positive marks from owners who wanted to run a red dot without machining costs. They appreciated that the cut was already there.

The textured grip holds consistently well, including in wet conditions, which comes up in carry-focused reviews. Magazine capacity at 10+1 is rated as a reasonable balance for a micro-compact, though owners who primarily range shoot sometimes mention wanting more capacity.

Recoil draws split opinions. At 18.3 oz with a 3-inch barrel, the Hellcat OSP moves noticeably more than a heavier compact. Most experienced shooters adapt quickly; newer shooters find it more challenging than a full-size or larger compact. Trigger feel is generally described as acceptable, though some owners who compare it to larger Springfield models or other brands find it could be crisper.

Overall, owners recommend it for carry. The compact dimensions, optics-ready slide, and reliable function are the consistent selling points.
