The Springfield Hellcat packs 11+1 (13+1 extended) capacity into one of the smallest micro-compact frames on the market, and the optic-ready OSP and slightly larger Hellcat Pro give you room to run a red dot. It's a high-capacity concealed carry standout — and it needs a holster that keeps it comfortable and hidden. Here's the best IWB holster for the Springfield Hellcat and Hellcat Pro, and the exact size to order.
The Best IWB Holster for the Hellcat: Mainstay™ Clipless IWB
For the Hellcat and Hellcat Pro, we recommend the Mainstay™ Clipless IWB Holster in size 7. Its clipless, silicone-coated body stays put inside the waistband with no belt clip to reveal you're carrying, fully covers the trigger guard, and flexes for comfortable appendix, strong-side, or small-of-back carry.
Since so many Hellcats wear an optic, match the size to your setup:
- Hellcat / Hellcat Pro (bare): size 7
- + red dot optic: size 7-RDO
- + weapon light: size 7L
- + optic and light: size 7L-RDO
Size 7 covers both the standard Hellcat and the longer-gripped Hellcat Pro.
Why the Mainstay Works for the Hellcat
The Hellcat's aggressive Adaptive Grip Texture is great for control but can chew on a stiff holster or your skin during all-day carry. The Mainstay's soft, flexible body sits comfortably against you while still locking the pistol in place and protecting the trigger. It's made in the USA and priced under $35 — one of our most popular IWB holsters.
