More shots per fill, lighter handling and refined German engineering make the HW100 X one of the most compelling PCP upgrades in years.
Introduction: The Quiet Benchmark of UK PCPs
The Weihrauch HW100 has always occupied a slightly different place in the UK airgun world. It is not a rifle that ever needed to shout for attention. Instead, it built its reputation quietly, through consistency, longevity and a kind of mechanical honesty that serious shooters recognise immediately. For many, the HW100 became a benchmark PCP: dependable, accurate and engineered with a confidence that came from Weihrauch’s long experience rather than trend-chasing design.
With the arrival of the new HW100 X, Weihrauch haven’t attempted to reinvent that formula. Instead, they have focused on the one thing owners have been asking for over the years: more usable shots per fill, without compromising balance, handling or the unmistakable HW100 shooting feel. The result is a rifle that feels reassuringly familiar, yet noticeably improved in ways that matter to UK airgun enthusiasts.
Consistent Performance: The New Ultra-Efficient Regulator
At the heart of the HW100 X is its new ultra-efficient regulator, and it is here that most experienced shooters will immediately see the appeal. Regulators are nothing new in modern PCPs, but Weihrauch’s approach has always leaned toward reliability and long-term consistency rather than chasing headline numbers. The new regulator is fitted directly into the valve block and is easily accessible, which is a welcome detail for shooters who actually live with their rifles rather than treating them as sealed units. In use, it delivers a remarkably stable shot curve, translating to tighter spreads and a feeling of predictability shot after shot. Whether you are shooting from a bench, working through a Field Target lane, or taking careful follow-up shots in the field, that consistency is what builds confidence.
Cylinder Improvements: More Shots, Less Weight
That regulator works in tandem with the new 250 bar cylinder, and this is where the HW100 X genuinely steps into new territory. Made from high-grade aluminium, the cylinder not only increases fill pressure but also reduces overall weight. On the standard length rifle the reduction is around 360 grams, with the carbine shedding approximately 240 grams. Those numbers might not sound dramatic on paper, but in the hands the rifle feels subtly livelier, especially for shooters used to carrying an HW100 over longer sessions. Balance remains distinctly Weihrauch, slightly forward but reassuringly planted, while the reduced weight makes offhand shooting feel less fatiguing.
Of course, the headline benefit of the new cylinder is shot count, and Weihrauch have delivered in a way that feels genuinely useful rather than theoretical. In .177 calibre, the full-length HW100 X now offers up to 210 shots per fill, representing a roughly 90 percent increase over the previous model. In .22 calibre, the improvement is arguably even more striking, with up to 250 shots per fill, nearly an 80 percent increase. For UK shooters who value long sessions without breaking rhythm to refill, this is a significant upgrade.
Ergonomics and Stock Design: Comfort Meets Functionality
Weihrauch’s attention to refinement is also evident in the launch version of the HW100 X Sporter Laminate Adjustable. This model celebrates the evolution of the platform without drifting into unnecessary excess. The new laminate sporter stock is visually striking without being loud, and it retains the understated practicality that UK shooters tend to appreciate. The adjustable cheek-piece allows proper eye alignment with modern optics, which is increasingly important as scopes become more specialised. The new ventilated butt pad offers improved comfort and shoulder purchase, especially during longer shooting sessions, while remaining practical for field use.
One of the most welcome ergonomic updates is the inclusion of ambidextrous safety levers on both sides of the action. This is a small change with a big impact, particularly for left-handed shooters who have historically had to compromise or adapt. The HW100 has always been praised for its fast fire side lever action, and that remains unchanged in feel and reliability, but the improved safety layout makes the rifle more inclusive without altering its core character.
Modern Features: Accessory Ready and Field Friendly
Modern accessories are also better supported thanks to the integrated M-Lok rail system. This brings the HW100 X neatly into line with how many UK shooters now set up their rifles, whether for bipods, torches or other accessories, without forcing a tactical aesthetic. It is a practical addition that feels well judged rather than bolted on for the sake of fashion.
As expected from Weihrauch, the HW100 X arrives fully formed, without the sense that essential features have been held back for higher trim levels. The high-efficiency silencer is effective and well matched to the rifle’s power delivery, producing a subdued report that suits both range and field use in the UK. The quick-fill system is straightforward and reliable, while the two-stage match trigger remains one of the highlights of the platform. It is crisp, predictable and adjustable, offering the kind of control that rewards good technique rather than masking poor habits.
Who the HW100 X is For: Experienced Shooters and Newcomers Alike
What makes the HW100 X particularly appealing is that it feels like a rifle designed for people who already understand airguns. There is no attempt to overwhelm with gimmicks or exaggerated claims. Instead, Weihrauch have focused on measurable improvements that enhance day-to-day shooting. More shots, less weight, improved ergonomics and the same precision engineering that has defined the HW100 line for years. For existing HW100 owners, the X represents a compelling evolution rather than a replacement driven by novelty. For newcomers to the platform, it offers a mature, refined entry point into one of the most respected PCP designs available in the UK.
Versatility and UK Shooting Applications
From a UK perspective, the HW100 X fits comfortably into a wide range of shooting disciplines. Its consistency and shot count make it well suited to club shooting and competitions, while its reliability and handling continue to appeal to hunters who value equipment that simply works. The increased efficiency also makes it a sensible choice for shooters who want to minimise time spent filling cylinders and maximise time behind the scope.
At Pellpax, we see rifles like the HW100 X as long-term investments rather than impulse purchases. This is a platform designed to be owned, maintained and enjoyed for years, not replaced at the first sign of a new model cycle. If you are considering adding the Weihrauch HW100 X to your collection, or upgrading from an earlier HW100, you can find full details and availability on the Pellpax website, along with expert advice to help you choose the right configuration for your shooting.
Conclusion: Precision Refined, Not Reinvented
The HW100 X does not try to redefine what a PCP air rifle should be. Instead, it quietly refines an already proven design, listening to what shooters asked for and delivering it with the same precision and restraint that have made Weihrauch a trusted name in the UK. For many enthusiasts, that approach is exactly what makes this rifle so appealing.
