Two Platforms, One Mission: Breaking Down the RHP and MHA

If you've been shopping for a rigid holster platform that eliminates the flex and wobble of factory polymer mounts, chances are you've come across two names from True North Concepts: the Modular Holster Adapter (MHA) and the Rigid Holster Platform (RHP). Both are machined from 6061-T6 aluminum, both feature a Type III hardcoat anodize finish, and both are proudly made in the USA. But they're not the same product, and understanding the differences between the two can help you build a holster setup that fits your specific needs.

At a Glance:

• The MHA uses a belt clamping system with aluminum belt bars, while the RHP uses a unique groove and boss belt interlocking system.

• The MHA offers 20 degrees of total cant adjustment (10° forward, 10° negative cant). The RHP provides 30 degrees (15° forward, 15° rearward).

• The RHP features a curved back face for increased belt contact area and comfort, plus recessed hardware pockets to protect mounting hardware from abrasion damage.

• Both platforms are compatible with all 3-hole Safariland pattern holsters, the Safariland QLS, and True North Concepts leg strap options.

• Both are constructed from domestically sourced 6061-T6 aluminum with a Mil-Spec Type III hardcoat anodize finish for maximum durability.

The MHA was the original holster adapter from True North Concepts, designed to solve a widespread problem with factory polymer belt adapters. The RHP came later as an expansion of the MHA's core design, adding new features while keeping the same commitment to stability and precision.

What Is the Modular Holster Adapter (MHA)?

The MHA was built from the ground up to replace the flexible polymer adapters that ship with most duty holsters. These factory mounts are known for shifting, flexing, and sliding on the belt during movement, which creates inconsistency in draw stroke and overall comfort. The MHA eliminates that problem entirely.

At the heart of the modular holster adapter is a clamping system that sandwiches the belt between the aluminum body of the adapter and two color-matched aluminum belt bars. This clamping force, combined with the 0.190" thick 6061-T6 aluminum construction, creates a rigid, flex-free platform for your holster. Once properly installed, the MHA does not move on your belt. Period.

The MHA supports a mid-ride mode of carry, positioning your holster below the belt line so it clears body armor, pouches, and other gear. It fits all 3-hole Safariland pattern holsters and supports quick-detach systems including the Safariland QLS, MLS, and ELS. Holsters mounted to the MHA accommodate 10 degrees of forward cant and 10 degrees of negative cant for a total range of 20 degrees. It also includes three vertical holster height adjustment points, spaced 1/2" apart, descending from the top mid-ride mounting point.

One of the MHA's standout qualities is its versatility in belt compatibility. The included belt bars are sized and spaced to thread through MOLLE webbing on battle belts, making it a popular choice among military and law enforcement professionals using minimalist setups from brands like GBRS Group, AXL, and Ferro Concepts. Alternatively, the bars can bolt directly to any standard trouser belt or duty belt up to 2.25" wide. The adapter also includes top mounting points for accessories like the Tek-Lok and MALICE clips.

Every MHA comes with a complete mounting hardware kit, including screws, posts, spacers, and threadlocker. It's available in Black, Dark Earth, and Olive Drab Green, and carries a lifetime, no-questions-asked replacement guarantee.

For users who want additional stability during high-movement activities, the True North Concepts Leg Strap Kit attaches directly to the MHA. The kit features a specialty bracket with four height positions, letting you customize exactly where the holster leg strap sits relative to the bottom of the adapter.

What Is the Rigid Holster Platform (RHP)?

The RHP was developed to expand on the key features of the MHA while introducing several design upgrades aimed at increased comfort, stability, and adjustability. Like the MHA, it's machined from 6061-T6 aluminum and finished in a non-reflective Type III hardcoat anodize. It's also made in the USA and compatible with all 3-hole Safariland pattern holsters, the Safariland QLS system, and popular attachments like the Blade-Tech Tek-Lok.

Where the RHP differs starts with its belt attachment method. Instead of a clamping system, the rigid holster platform uses a unique groove and boss belt interlocking system. This design locks the platform to the belt with zero shift or rotation, even during high-intensity movement. It supports belts up to 2.25" wide and maintains a mid-ride carry position.

The RHP also offers a wider range of cant adjustment than the MHA. With 15 degrees of forward cant and 15 degrees of rearward cant, it provides a full 30 degrees of total adjustment. This gives users more flexibility to fine-tune their draw angle based on personal preference, body type, and loadout configuration.

Three additional features set the RHP apart from the MHA:

• Curved back face: The back of the RHP is contoured to match the curve of the body, increasing the belt contact area. This distributes pressure more evenly across the belt and improves comfort during extended wear on a duty belt or battle belt.

• Recessed hardware pockets: The mounting hardware sits within recessed pockets built into the platform, protecting screws and posts from impact and abrasion damage. This is a practical upgrade for users in demanding field environments.

• Vertical height adjustment points at .525" increments: The RHP includes three adjustment points spaced at .525" apart, giving users precise control over holster ride height.

The RHP is also fully compatible with the True North Concepts Leg Strap Kit (LSKP), making it a strong option for anyone who needs extra retention during dynamic movement. For users in patrol or duty roles who want a shorter profile, True North Concepts also offers the RHP Patrol (RHPP), which measures 6.25" compared to the standard RHP's 7.50" length.

Side-by-Side Comparison

Both holster platforms share a lot of DNA. They're both machined from 6061-T6 aluminum, finished in Type III hardcoat anodize, and built in the USA. They both support Safariland 3-hole pattern holsters, the Safariland QLS, and mid-ride carry. And they both come with a lifetime replacement guarantee from True North Concepts.

Here's where they split:

• Belt attachment: The MHA clamps the belt between the adapter body and aluminum belt bars. The RHP interlocks with the belt using a groove and boss system.

• Cant adjustment: The MHA offers 20 degrees total. The RHP offers 30 degrees total.

• Comfort features: The RHP includes a curved back face and recessed hardware pockets. The MHA has a flat-back profile.

• MOLLE compatibility: The MHA's belt bar design threads naturally through MOLLE webbing, making it extremely popular on minimalist battle belts. The RHP also offers MOLLE compatibility, though True North Concepts recommends mounting it between the belt and body for long-term durability, as repeated use through molle webbing can accelerate wear.

• Accessory compatibility: The RHP explicitly supports a wider range of quick-disconnect systems, including Blade-Tech Tek-Lok and paddles, alongside the Safariland QLS.

Which One Should You Choose?

Neither platform is objectively better than the other. The right choice comes down to how you plan to use it and what features matter most to your setup.

The MHA is an excellent choice for users who run MOLLE-based battle belts and want a proven, straightforward clamping system that locks their holster in place. Its popularity across military, law enforcement, and competition communities speaks for itself. If your priority is a lightweight, no-nonsense modular holster adapter with strong MOLLE compatibility, the MHA is hard to beat.

The RHP is the right pick for users who want the most cant adjustment available, value the added comfort of a curved back face, and prefer the security of recessed hardware pockets. If you're wearing your rig for long shifts on a duty belt or need every degree of fine-tuning for your draw angle, the RHP's expanded feature set is worth the look.

Both platforms pair well with True North Concepts accessories, including the MHA Velcro Bridge, holster pads, and leg strap kits. And both can be outfitted with the Universal Holster Mount if you're running a non-Safariland holster.
