The Springfield Hellcat family has expanded once again. The newest member/model is the Springfield Hellcat RDP. RDP stands for “Rapid Defense Package“, and as you can probably tell from the name it’s an upgunned version of the original Hellcat OSP micro-compact. That P stands for Package, by the way. Not Pistol. Which for some reason I keep typing.
But I digress.
Hellcat RDP Upgrades
Self Indexing Compensator
There two most immediately obvious new features of the RDPackagedammitnotPistol are the micro red dot sight up top and the pistol comp out front. We’ll talk more about the former in a moment. The latter is what they call a “Self Indexing Compensator”. It’s attached to the weapon via a 3.8 in. threaded barrel and is, as with all comps, intended to reduce muzzle flip and mitigate felt recoil.
The 9mm cartridge is hardly an earth-shaker when it comes to recoil, but it does affect accuracy, particularly when used in a small frame handgun with a short barrel. And while there will almost certainly be one or more “Ithaca Giant” Conley types who’ll deride the need or desirability of a (particularly 9mm) pistol comp, let’s just agree that they work as advertised and are desirable in certain circumstances.

We’ll revisit that fact and whatever comments show up at some point in the future (perhaps in my review).

Springfield describes their comp thusly:
Tame muzzle rise with the patent-pending Springfield Armory Self Indexing Compensator made of aircraft-grade Hardcoat anodized aluminum. This compensator vents gasses upward putting downward pressure on the muzzle greatly reducing muzzle rise for better control and faster follow-up shots.
The Hellcat RDP features a compact and capable compensator that maximizes rapid-fire muzzle control. Machined from 8082 aluminum and anodized matte black, the compensator has a patent-pending Self Indexing design that makes installation or removal easy and does not require shims or additional parts for proper timing.

Springfield Armory HEX Optics
Wasp Red Dot Sight
Now on to the red dot sight you see up top. That isn’t one of their previous model OSPs with a Holosun, Swampfox Sentinel, or Shield RMSc aboard. That is one of the two new optics from the HEX series of red dots released by Springfield Armory concurrently with the RDP.
According to the manufacturer’s specs, the Wasp is a
• 3.5 MOA red dot sight
• with a red dot (vs. green, mind you) and a
• half-MOA adjustment capacity and
• 90 MOA for windage and elevation, in a
• Springfield Micro Footprint (Shield RMSc), powered by a
• CR2032 battery rated for 65k hours of use
SA says,
The Wasp is always powered and features an auto-dimming sensor that regulates proper dot brightness based on ever-changing ambient light conditions. Precision machined from 6061 T6 Hardcoat anodized aluminum and outfitted with a scratch-resistant, anti-glare glass lens, the HEX Wasp is a rugged, reliable companion for your optics-ready everyday carry.
Springfield Hellcat RDP: the Remainder
The RDP also features an optional, low profile, ambi manual safety at the rear of the frame, the new SA Gen 2 hellcat trigger, and their “Tactical Rack U-Notch” rear sight. That sight can be co-witnessed with the Wasp.
Hellcat Gen 2 Trigger
The Hellcat RDP introduces the new Gen 2 Trigger. Recontoured for enhanced ergonomics, the Gen 2 trigger offers a more comfortable shooting experience and is a refinement of the most important interface between the pistol and the shooter.
Threaded Barrel
The 3.8″ hammer-forged barrel of the Hellcat RDP is extended and threaded and features a tough Melonite finish. (.5 x 28)
Tritium U-Dot Sights
The Hellcat RDP features high visibility tritium & luminescent front sight paired with a Tactical Rack U-Dot rear sight for easy target acquisition.
Optional Manual Safety
The Hellcat RDP is available with an optional ambidextrous manual safety on the frame of the pistol. It is a low-profile, unobtrusive design that features positive engagement and is simple and easy to operate both left or right-handed.

Hellcat RDP Review: Paul Carlson on The Armory Life
Paul Carlson, a frequent contributor here at The Mag Life, recently reviewed the RDP on The Armory Life, Springfield Armory’s blog.
Here’s an excerpt:
While you can have the coolest accessories and features on your carry gun, there is one, single part that is the most important interface with the shooter — the trigger. As with every product offered, Springfield Armory is constantly considering every product it offers and how it can enhance or refine the designs. To that end, the Hellcat RDP features the new Gen 2 Trigger.
Recontoured for enhanced ergonomics, the Gen 2 trigger is designed to offer the most comfortable shooting experience for the broadest range of shooters. Designing such a small pistol to fit a broad range of hand sizes can be a challenge, but the Gen 2 trigger features a higher hinge point and a smooth face to allow shooters with shorter or longer fingers to comfortably engage the trigger…
Throughout this review, I found that the combination of the HEX Wasp, the Gen 2 trigger, and the compensator allowed me to increase my precision. After getting the gun sighted in, I was able to consistently drill a 2″ target at 10 yards with rapid follow-up shots. With practice, I’m sure my skills with the Hellcat RDP will improve even more.
