WHAT'S IN THE BUNDLE:
Hellcat Pro Accessories Bundle
Our Custom Springfield Hellcat Upgrades Bundle is designed to fit and function in all Springfield Hellcat Micro-Compact models, including RDP, OSP, Pro OSP, and Hellcat 380 / .380 ACP variants. This bundle represents the pinnacle of Hellcat aftermarket performance, offering maximum results and exceptional value in one comprehensive package. This kit is the best solution to factory Springfield Hellcat problems.
Springfield Hellcat Titanium Performance Striker Assembly
This precision CNC machined Titanium Striker reduces lock time, addressing common issues like light strikes and primer drag experienced with the OEM Striker. It's the optimal solution for reducing Springfield Hellcat Primer Drag!
Note: Compatible with Hellcat 380 / .380 ACP models. Some .380 frames or factory spring sets may vary slightly — verify your specific model/configuration before installation and test function after installation.
Springfield HELLCAT Flat Trigger MOD-2 Upgrade
Our precision CNC machined 6061 Aluminum Springfield Hellcat Flat Trigger is a significant upgrade over the factory plastic trigger, offering superior performance and addressing binding issues. This matched set includes an aluminum trigger frame and safety blade, setting a new standard for aftermarket performance.
Note: The flat trigger MOD-2 is compatible with Hellcat 380 / .380 ACP models. On some .380 variants, trigger geometry and safety blade engagement should be verified during final function checks.
Springfield Hellcat Trigger Spring Kit & Stainless Steel Striker Sleeve
The most vital aspect of all Springfield Hellcat accessories is to enhance the function and reliability of the pistol. Some common Springfield Hellcat problems arise when aftermarket parts fail to account for the impact on other internal components. The bundle includes a precision CNC machined 300 Series Stainless Steel Striker Sleeve as a durable replacement for the fragile factory plastic sleeve, particularly important when installing a lighter striker spring.
Note: This spring kit and stainless sleeve are compatible with Hellcat 380 / .380 ACP. However, .380 factory spring rates and tolerances can differ from 9mm variants — both the sear spring and striker/firing pin spring must be installed and a post-installation function & safety check is required. If your Hellcat 380 has a manual thumb safety, remember the additional installation step for safety-equipped models.
This All-In-One Pro Performance Bundle is a compilation of the best Springfield Armory Hellcat accessories aimed at improving performance and reliability. All components are precision CNC machined, made in America by combat veterans, and designed to correct factory Springfield Hellcat problems, providing a level of action enhancement and reliability that is simply untouchable.

Hellcat Pro Bundle Fail
I had a gunsmith install the Hellcat Pro Accessories Bundle. The trigger felt great, MUCH better than the factory trigger. However, the trigger fails to reset reliably. I can't get 3 consecutive shots off without a reset failure. I returned it to the gunsmith and he was unable to resolve the issue. I will keep the striker assembly, but replace the trigger kit with an Apex kit. I am really disappointed. I put a Mcarbo kit in my P365XL and it felt great, but I got 10 light strikes out of 30 rounds. I bought a titanium striker assembly, and that fixed the issue. It should have worked without forcing me to replace the striker... So, not so impressed with this company's products.
Best upgrade for the hellcat & BEST TRIGGER
I just bought and installed the kit myself. This was the first time that I ever modified a firearm. The instructional video was clear and easy to follow. I HATE the stock trigger on the Hellcat. I wish it came with the same trigger as the XDm. The mCarbo trigger is great and performs exactly like I was hoping it would. Nice, clean, and clear wall before complete engagement. I use my Hellcat as my daily carry and for competing in IDPA and PCC. I normally compete in three-position rifle with my M1A at 200 yards. I just could not deal with the stock trigger in the hellcat anymore. This performance kit does everything that I wanted it to.
Easy for novice
Went to the range earlier after installing this, and the difference between the stock trigger and parts and the upgraded ones is incredible. My wife and I’s shot groups were waaaaaay better. I did the install myself and just had one of those Amazon tech screwdriver kits with a bunch of different heads, and I used some of the flat head ones as punches, and a roll of tape. Installing the roll pin in the trigger was the hardest part but doable with some patience. Also customer service was super responsive and helpful. 10/10!
What the Hellcat should be
I bought the Pro Comp and was ready to trade it in after the 2nd trip to the range. Bought it to replace may Glock 27 as a carry gun. Trigger was one of the worst out of the box I ever saw. Installed the striker assembly and ran some rounds through it and felt a big improvement already. Installed the trigger and dialed in the creep screw and it was like a different gun. All parts in the kit are precision made and top quality. Easy installation and perfect fit.
Must have upgrade for the Hellcat to perform the way it was designed to perform!
It’s a different gun
Great Price
Great Quality
Great Install Video
Went in without a hitch, The quality is +A, Smoothed out the pull completely, Now an even bigger pleasure to shoot
Wow! Night and Day!!
Wow! Night and Day!! I recently installed the M*CARBO performance package for my Hellcat Pro OSP. Prior to that I had made a couple of trips to the range and was disappointed in the Hellcat Pro's performance. I had experienced frequent "return to battery" problems, and struggled with the awful stock trigger (too heavy, too mushy, not a clean wall or break, an unsatisfactory reset). At least I was able to zero the Crimson Trace red dot, and I found the gun was inherently accurate. I ordered the M*CARBO package and installed it per Chris' video. I also polished all surfaces that exhibited wear marks (witness marks). The new trigger, stainless steel striker sleeve, titanium striker, striker spring, sear spring, and striker block safety spring, all went in without a hitch. Yesterday was a stellar day at the range: The trigger was a dream - just the right weight (about 4.5 lbs), no grit, no mush, a shorter take-up (thanks to the adjusting set screw), a crisp break, and a short positive reset. Now it's a dream gun!! Thanks, M*CARBO!
Worth every cent!
Just got back from the firing range after the full upgrade on my Hellcat Pro Comp OSP, my God, I can’t believe how accurate this gun is now! 1” groups at 10 yards all day long. Trigger is a nice 4.5 lbs. with a very short reset. Very happy, install was straightforward.
M.Carbo - Apex
This is my first M.Carbo trigger kit install. I've always used Apex. My opinion, This kit is the best I've used. Not that Apex is a bad choice just my opinion. Factory test pulls (3 pull average was 5.9/5.8/6.12) After the kit install (3 pull average 4.2/4.6/4.4) Crisp, great feel, awesome reset. Very satisfied with this purchase. 100% recommend.
Has anyone edc this trigger and should I be worried about it going of uncommanded with the new sear spring?
Yes we have customers that have upgraded their EDC with our kit. We drop test and confirm safety.
will this trigger kit work on a Hellcat Pro California compliant even if I removed the magazine safety disconnect?

Do you plan to develop a kit for the Hellcat Pro Comp?
If the Hellcat Pro Comp is the standard hellcat is a standard Hellcat/Hellcat Pro slide/platform and not a different model, our current trigger is compatible
Will this trigger kit reduce take up & more crisp brake on stock trigger?
Yes - the kit will help with that
I purchased the Springfield Hellcat Pro Accessories Bundle and am concerned that it might not fit the Hellcat Pro Comp. Should I return it after I receive it. or will it fit?

On the hellcat pro acc bundal..the guy shows one full turn on the trigger screw.which way will lighten the trigger and what way hardens trigger.He said that is what he uses..The small tork screw for ajustment on trigger...ty
Turn the little adjustment screw clockwise (in) to make the trigger heavier (stiffen it). Turn it counter-clockwise (out) to make the trigger lighter
Could this bundle be used with the XD-S Mod.2 45 acp?
The XD-S Mod.2 .45 ACP is a distinct platform with different internal mechanisms, including variations in the striker system, trigger geometry, and spring dimensions. Due to these differences, the components in the Hellcat Pro Accessories Bundle are not compatible with the XD-S Mod.2 .45 ACP.

Is the trigger reset shorter?
This kit is designed with a pre-travel adjustment fixture custom-molded to fit the Hellcat trigger. This makes tuning your trigger simple and secure, letting you fine-tune for performance with confidence.

I left a review. Why can I only see 4 reviews?
Must have asked this question on another item. Whoops. I was wondering if and when these would be coming back into stock? Really hoping to purchase a kit soon.
Hey is this compatible with the Pro version
Yes, it does work in the pro version.
is everything included safe for conceal carry?
I'm going to say no. I installed my trigger system in my hellcat pro. It worked perfectly for about 4 magazines. In the middle of shooting today the trigger quit resetting, so I tried to pull the trigger forward to reset it and it fired. I came here to try to troubleshoot this issue.
