The compact PCP air pistol market has grown quietly but steadily in the UK over the past few years. Where once shooters had limited choice, we’re now seeing genuinely well-engineered pistols that deliver consistency, refinement and proper shootability — all within UK sub-6 ft/lb limits.
Reximex have been one of the brands pushing this forward, and their Mito platform is a strong example of how far modern PCP pistols have come. Compact, regulated, and thoughtfully designed, the Mito range offers serious performance in a small, approachable package.
Two of the most popular variants are the Reximex Mito RP11 and the Reximex Mito RP Race. On paper, they’re very similar. In the hand, and on the range, the differences become more interesting.
So which one is right for you? Let’s take a proper look.
The Reximex Mito Platform – What They Share
Before getting into the differences, it’s important to understand what makes the Mito platform appealing in the first place — because both pistols share the same core DNA.
Both the RP11 and RP Race are:
- Pre-Charged Pneumatic (PCP) air pistols
- Fully UK-legal in sub-6 ft/lb configuration
- Available in .177 or .22 calibre
- Factory fitted with a regulator
- Equipped with a side-lever cocking system
- Compact, with a 330mm overall length
- Filled to 250 BAR via a removable 50cc aluminium air tube
That regulated action is key. Many compact PCP pistols feel inconsistent across a fill, but the Mito’s regulator keeps velocity predictable and shot-to-shot variation low. Whether you’re punching paper targets or plinking in the garden, consistency matters — and both Mitos deliver it.
In short: you’re not choosing between better or worse engineering. You’re choosing between different interpretations of the same solid platform.
Reximex Mito RP11 – Modern, Solid, Tactical
The Mito RP11 is the more overtly modern-looking of the two. With its aluminium 1911-style pistol grip and clean metal finish, it leans towards a tactical, industrial aesthetic that will immediately appeal to shooters who like a contemporary feel.

In the hand
At 1005 grams, the RP11 is the heavier of the two pistols — and that weight is noticeable, but not in a negative way. It gives the pistol a planted, reassuring feel, especially when shooting offhand. The aluminium grip adds rigidity and a sense of durability, and the balance feels neutral rather than front-heavy.
For shooters coming from firearm-style pistols or heavier air pistols, the RP11 often feels instantly familiar.
On the range
In .177, the RP11 really shows its strengths. The extra mass helps settle the pistol between shots, and the regulated action delivers a consistent, flat trajectory that makes precision shooting straightforward at typical air pistol distances.
The side-lever cocking system is smooth and positive, feeding from a 9-shot magazine in .177 (7-shot in .22). There’s nothing flimsy or toy-like here — the action feels deliberate and well put together.
Who is the RP11 for?
The RP11 suits shooters who:
- Prefer a modern, tactical aesthetic
- Like a pistol with a bit of heft and stability
- Want something that feels robust and purposeful
- Enjoy structured practice sessions and precision shooting
It’s a pistol that rewards control and consistency, and it feels built for regular use rather than occasional novelty.
Reximex Mito RP Race – Lightweight, Balanced, Sporty

The Mito RP Race takes the same mechanical platform and shifts the emphasis toward balance, weight reduction, and competition-inspired ergonomics.
Visually, it stands apart thanks to its synthetic grip paired with a walnut stock — a combination that gives it a distinctive, almost hybrid look: modern but with a nod to traditional sporting design.
In the hand
At just 900 grams, the RP Race is noticeably lighter than the RP11. That difference doesn’t sound huge on paper, but in use it’s immediately apparent.
The pistol feels:
- Faster to bring on target
- Easier to hold for extended sessions
- Less fatiguing during long practice runs
The grip shape and materials offer excellent control without feeling bulky, and the balance encourages a relaxed shooting style rather than forcing you to fight the weight.
On the range
The lighter build doesn’t mean reduced performance. The factory-fitted regulator ensures the same consistent delivery as the RP11, and accuracy remains excellent in both calibres.
In .22, the RP Race is particularly pleasant to shoot. The calibre’s naturally calmer firing cycle pairs well with the lighter frame, making the pistol feel smooth and forgiving — ideal for relaxed plinking or informal target work.
Who is the RP Race for?
The RP Race is ideal for shooters who:
- Prioritise light weight and comfort
- Shoot for longer periods
- Prefer a more sporting or competition-inspired feel
- Want a pistol that feels agile and responsive
It’s the Mito for shooters who value handling above outright mass.
.177 vs .22 – Does Calibre Change the Choice?
Both pistols are available in .177 and .22, and calibre choice can influence which model feels like the better fit.
- .177 calibre offers a faster, flatter pellet trajectory and is often preferred for precision target shooting.
- .22 calibre delivers a slower, more stable pellet that can feel more forgiving at close range.
In practice:
- Shooters choosing .177 often gravitate toward the RP11, where the extra weight complements the calibre’s snappier feel.
- Shooters choosing .22 often enjoy the RP Race, where the lighter frame and smoother firing cycle work beautifully together.
That said, both combinations work well — this is about preference, not limitation.
RP11 vs RP Race – Side-by-Side Summary
Choose the RP11 if you want:
- A more modern, tactical look
- Aluminium 1911-style grip ergonomics
- A slightly heavier, more planted shooting feel
- A pistol that feels robust and purposeful
Choose the RP Race if you want:
- A lighter, more agile pistol
- Reduced fatigue during long sessions
- A sportier, competition-inspired aesthetic
- A blend of modern materials with classic walnut
Both offer:
- Regulated PCP performance
- Side-lever operation
- Compact dimensions
- UK-legal sub-6 ft/lb compliance
- Excellent consistency for their size
Final Thoughts: Two Flavours of the Same Strength
The Reximex Mito RP11 and RP Race aren’t competitors — they’re two expressions of the same capable platform.
The RP11 feels solid, modern, and confidence-inspiring.
The RP Race feels light, balanced, and refined.
Neither is objectively “better”. The right choice depends on how you shoot, how long you shoot for, and what feels right in your hand.
At Pellpax, we’ve seen both models appeal to different types of shooters — and that’s exactly how it should be. Whichever Mito you choose, you’re getting a compact PCP air pistol that delivers real performance, not just clever design.
