New Install Video: M*CARBO Springfield Hellcat Pro Performance Bundle

Wed, 07 Jun 2023 12:42:50 -0500

We've heard your calls and read your emails, and we're here to finally answer the burning question that many of you have been asking: "Will our Hellcat Parts work in the Hellcat Pro? Will it work in a regular Hellcat? With the thumb safety? Without the thumb safety?"

Yes, they absolutely do! But to ensure clarity and provide a detailed guide, we've prepared a Brand-New Video all about how to install the M*CARBO Springfield Hellcat Pro Performance Bundle as well as its compatibility with various Hellcat models.

What's Inside the Pro Performance Bundle?

Our Pro Bundle includes our Springfield Hellcat Flat Trigger, manufactured from durable 6061 aluminum, providing a sturdier, more comfortable feeling than the plastic stock variant. A common complaint about the plastic trigger was the occasional pinch. To combat this, we've designed a crossbar that comes all the way down, eliminating any pinching that may occur.

The bundle also comes with a custom pretravel adjustment fixture, allowing you to adjust the pre-travel according to your preference.

One of the stellar features in the Pro Bundle is our Springfield Hellcat Titanium Striker Assembly. Titanium ensures strength, reliability, and lightness. Our ingenious engineers have also revamped the connecting lug face for a smooth, crisp, and beautiful pull.

Furthermore, our Springfield Hellcat Trigger Spring Kit is included to reduce your overall trigger pull weight.

Let's Get Down to Installation!

You might be wondering, "How do I install these fantastic features?" We've got you covered. The video will guide you step by step through the installation process.

To start with the installation, you'll need the following:

A Hellcat (As stated before, it'll work with the pro or anything else)
Safety glasses
Synthetic Grease w/ PTFE
Loctite 242 Blue
A Hammer
A 3/32" Punch
A 1/16" Punch
A Bench Block

Before you get started, make sure your firearm is cleared. Once you've done this, you're all set to begin the installation!

Don't Miss Out!

We're extremely excited about this new video and hope it will help all our Hellcat users. Not only does it provide a thorough demonstration of the installation process, but it also brings you a closer look at the Pro Performance Bundle and all its exceptional components.

Check out the video and tell us what you think! And, as always, we appreciate your continued support and feedback. Happy shooting, everyone!

Ruger LCP MAX Review - A Modern Day Derringer

Tue, 01 Nov 2022 10:51:47 -0500

Ruger LCP MAX Review - A Modern Day Derringer

Have you been searching tirelessly for an incredibly concealable, high-capacity micro-compact to tuck in your skivvy shorts? Or perhaps something handy to carry in your robe for those quick mail-grabbing moments? Look no further, as this Ruger LCP Max review will provide insights into why Ruger’s LCP and LCP MAX might just be your go-to options.

This firearm is, without a doubt, the smallest carry pistol I recommend, yet it delivers a beautiful shooting experience for its size. Today at M*CARBO, we’re showing some love to our little friend, the LCP, addressing all your potential Ruger LCP Max problems and discussing Ruger LCP Max accessories to enhance your experience.

Specs

Why LCP is a Good EDC Pistol

Whether you are a concealed carry novice or a seasoned carrier, you understand that concealability is pivotal when deciding on a CCW. The Ruger LCP’s compact size earns its reputation as the ideal “pocket” carry pistol. Ruger has astonishingly fitted a 10 round .380 ACP capacity into a pistol the size of a one-shot Derringer, alleviating any Ruger LCP Max problems regarding size. It even includes a low-profile pocket holster right out of the box, making it the perfect micro-compact for small tote or coin purse carry.

Ruger has meticulously designed the LCP Max for all-around comfort. With a grip slightly longer than the LCP II, it offers a more comfortable grip, addressing any holding issues associated with tiny micro-compacts. The ergonomics of the LCP MAX make it solid to hold when firing, making it a viable backup concealed carry in an ankle or pocket holster, especially when desiring to wear more casual clothing.

.380 Skepticism

Despite its benefits, the .380 ACP has faced criticism, with some questioning its effectiveness as a self-defense round. Surprisingly, a few .380 manufacturers meet the FBI ballistics protocol for bullet penetration. The Federal .380 ACP 90 grain Hydra-Shok round not only meets but exceeds FBI standards, making it a highly recommended round for those using the LCP MAX as a daily carry.

LCP MAX Upgrades

Ruger has paid heed to customer feedback, addressing the original LCP’s shortcomings and introducing commendable improvements with the LCP MAX. A significant upgrade includes an increased mag capacity from 6 to 10+1 (12+1 with the extended grip mag), achieved through the reengineering of the magazines for double-stack capacity. The LCP MAX boasts the highest round capacity for its size, accompanied by a slight increase in width, enhancing the CCW.

The newer grips offer more surface area for better hold and recoil control, alongside upgraded iron sights featuring a Tritium front sight for faster target acquisition. The introduction of the "Secure Action" trigger and the ambidextrous magazine release are other notable improvements, enhancing the user experience and addressing potential Ruger LCP Max problems.

Final Thoughts

Ruger has invested significantly in this compact handgun, offering a great CCW option for those struggling with 9mm handgun recoil. It is incredibly suitable for quick outdoor tasks, eliminating the need for extra accessories, unlike carrying a larger Glock 17. With a reasonable Ruger LCP Max price tag of around $470, it stands as one of the best in its class.

For those seeking to optimize their Ruger experience, check out our MCARBO Ruger LCP, Ruger LCP 2, or Ruger LCP MAX upgrades. Whether it’s enhancing your firearm with Ruger LCP Max accessories or exploring the Ruger LCP Max 380 review for more insights, MCARBO has you covered.

Sig P365 vs Springfield Hellcat: Micro-Compact Giants Go Head-to-Head

Tue, 11 Oct 2022 07:59:11 -0500

Sig P365 vs Springfield Hellcat: Micro-Compact Giants Go Head-to-Head

In the fiercely debated competition of Sig P365 vs Hellcat, it's challenging to definitively declare a winner. The Sig P365 vs Springfield Hellcat debate has brought firearms enthusiasts to consider every element of these compact titans, exploring dimensions, frame, slide, sights, safety, trigger, magazine capacity, firing and recoil, quality and aesthetics, and, of course, price.

Dimensions and Frame

Examining the dimensions, the Springfield Hellcat and Sig P365 are almost identical in size and weight. However, a closer inspection reveals the Springfield Hellcat’s compactness in height, setting it apart. When it comes to frames, the Hellcat offers a wider grip, potentially benefiting those with a preference for a more substantial hold. However, this is contrasted by the P365’s longer length, offering a snug grip around the magwell, particularly beneficial for those with larger hands.

Slide and Sights

The slide of the Sig P365 is often lauded in Sig Sauer P365 reviews for its superior design and smooth operation, outperforming the Hellcat. The serrations on the P365 are notably more defined, aiding in the firearm’s usability, especially in high-pressure situations.

Sights are a significant differentiator in the Springfield Hellcat vs Sig P365 battle. Springfield opts for Tritium U-dot sights, creating a contrasting design compared to the Sig P365’s varied sight options, depending on the model. The base and X-series models of the Sig P365 offer X-RAY3 Day/Night sights, providing a clear sight picture, a feature often praised in Sig Sauer P365 review discussions.

For those keen on optics, both brands present higher-end models equipped with optics-ready slides, namely the Hellcat OSP and the Sig X-Series.

Safety and Trigger

Safety is paramount, and both the Sig Sauer P365 and Springfield Hellcat uphold this principle, incorporating manual safety in their State Compliant models. The Hellcat, however, gains an edge with its standard trigger safety.

Trigger design and responsiveness are pivotal for many users, and both the Sig P365 and Hellcat offer unique experiences. The P365 is renowned for its smooth pull, while the Hellcat offers a more definitive trigger pull, catering to varied preferences.

Magazine Capacity and Firing Experience

On the firing range, magazine capacity becomes a pivotal factor. The Hellcat surpasses the base model P365, boasting an 11+1 standard mag capacity. However, the Sig P365 X-Series, especially the XMACRO, holds a commanding lead with a whopping 17+1 capacity.

Recoil management is also essential, and the P365’s longer frame design proves advantageous, especially when paired with the compensator-integrated models like the P365 XMACRO and Hellcat RDP.

Quality, Aesthetics and Price

Quality-wise, both firearms are on par, with the Hellcat’s frame feeling sturdier and the P365’s slide showcasing unparalleled smoothness. A point of distinction is the P365’s American-made origin, compared to the Hellcat’s production in Croatia. Aesthetically, the sleek design of the Sig Sauer P365 slightly overshadows the Springfield Hellcat.

The Springfield Hellcat price stands around $600 for the base model, which is somewhat higher compared to the Sig Sauer P365 price of around $500. However, some might argue that given the Hellcat’s features and performance, this price difference is justified. The upgraded models, like the Sig P365 XMACRO and Hellcat RDP, have higher price tags, around $800 and $1000 respectively, with each offering features that warrant the cost.

The Results

Determining the winner in the Sig P365 vs Springfield Hellcat debate is a challenging endeavor. Both firearms are award-winning micro-compacts, each with its unique advantages. The Springfield Hellcat review highlights its compactness and sturdiness, making it a solid choice for those seeking a smaller carry. In contrast, the Sig Sauer P365 reviews underscore its versatility, accommodating design, and overall performance, especially in the XMACRO model. Ultimately, your choice between the Hellcat vs Sig P365 will hinge on your personal preferences, shooting style, and specific needs.

What is a Zero?

Mon, 08 Aug 2022 21:50:10 -0500

A zero is the alignment of the sights with the bore of the rifle so the bullet will impact on the target at the desired point of aim. When the aim, the sights, and the bore coincide on the same point, it is called the zero. There are two zero ranges, near and actual. These are the two locations that the bullet crosses the line of sight.
