Apex 9mm Drop-In Barrels for Hellcat

The Apex 9mm Drop-In Barrel for Hellcat pistols is a straight-up replacement for your factory barrel. No gunsmith, no fitting, no hassle. Just swap it in and get back to shooting. We stock both the threaded and non-threaded versions, so you pick what fits your setup.

Threaded Barrel – $200
If you want to run a suppressor or compensator, this is your part. It features 1/2-28 threads to fit standard muzzle attachments. The undercut thread intercept means you can swap accessories without fighting the threads. Machined from premium heat-treated, button-rifled steel blanks with a 1:10″ twist rate. The Black ArmorLube finish is tough—built for long-term durability, not just looks.

• Direct drop-in for Hellcat: no fitting required
• Threaded 1/2-28 for standard muzzle devices
• Undercut thread intercept for easy accessory swaps
• Heat-treated, button-rifled steel blanks
• 1:10″ twist rate for reliable 9mm stabilization
• Black ArmorLube finish for corrosion resistance

Non-Threaded Barrel – $200
Prefer a clean, flush-fit barrel for carry or range use? This one replaces the factory 3″ barrel directly. Manufactured from heat-treated stainless-steel hammer-forged blanks—same 1:10″ twist rate, chambered for 9mm. The black Melonite finish is low-maintenance and holds up to heavy use. No fitting, no extra work. Just drop it in.

• Direct drop-in replacement for factory Hellcat barrel
• Heat-treated stainless-steel hammer-forged blanks
• 1:10″ twist rate, 9mm chamber
• Black Melonite finish for durability
• 100% manufactured in the USA

Both barrels are designed for the price-conscious shooter who wants a reliable upgrade without paying for frills. No need to send your slide out. No special tools. If you can field-strip your Hellcat, you can install this barrel. That’s the point.

Fitment notes: Fits all Hellcat and Hellcat Pro models (check your specific variant). Threaded barrel adds roughly 1/2″ to overall length. Non-threaded stays at factory dimensions. Both are drop-in with standard recoil spring assemblies.
