Every gun club has one, usually several. The Weihrauch HW100 has been Germany’s answer to the quality sporting PCP question since the mid-2000s, and in the UK it has built the sort of following normally reserved for springers like the HW97 and HW35. Search interest in second-hand HW100s is consistently among the strongest of any air rifle on Rightgun.uk, and this week’s data is no exception. Here’s why the HW100 endures, which variant to choose, and how to buy a used one with confidence.
What is the Weihrauch HW100?
The HW100 was Weihrauch’s first pre-charged pneumatic, and rather than dipping a toe in the water, the Rothenburg factory arrived with a rifle so thoroughly engineered it barely needed changing. It’s a regulated, multi-shot sidelever PCP feeding from a fourteen-shot rotary magazine, with a match-grade barrel, Weihrauch’s superb build quality and a trigger that lives up to the family name (the famous Rekord sits in their springers; the HW100’s own two-stage unit is every bit as usable).
In standard UK trim it runs at sub-12 ft·lb, making it available without a firearm certificate in England and Wales to those 18 and over (Scotland requires an air weapon certificate), with FAC-power versions available for certificate holders. Read our UK air rifle law guide if you’re new to the rules.
The variants: KT, KS, K, BP, and T
Weihrauch’s naming can baffle newcomers, so here’s the decoder. The full-length HW100 S wears a sporter stock; the T a thumbhole. The K models are carbines, shorter and handier, with the KT (karbine thumbhole) probably the most popular configuration in Britain, especially in laminate, which GSC search data shows UK buyers hunting for by name. The KS is the carbine sporter. More recently, the BP (bullpup) has brought the HW100 action into a compact format for hide and vehicle-based pest control, joined by adjustable-stock and synthetic options for all-weather work.
Calibre choice is the usual .177 or .22 decision. Hunters traditionally lean .22, target and general-purpose shooters .177; the rifle is superbly accurate in both.
Accuracy, consistency, and handling
The HW100’s party trick is consistency. The factory regulator keeps velocity remarkably flat shot-to-shot, and paired with the match barrel, it produces the kind of accuracy that wins field target club days out of the box. Shot counts are generous in both calibres from the standard cylinder, and the sidelever cycles with a slick, positive feel that rivals anything at the price.
Handling-wise, it’s a solid, substantial rifle; some find it a touch heavier than its great rival, the Air Arms S510, but that weight translates into steadiness on the aim. Fit and finish are exactly what Weihrauch’s reputation promises: deep bluing, tidy woodwork and an action that feels like it will outlast its owner. Many do; early HW100s from nearly two decades ago are still shooting sweetly on their original seals.
HW100 vs Air Arms S510
The eternal clubhouse debate. Both are regulated (on current S510 variants), both are sidelever multi-shots, both are superbly accurate, and the honest answer is that neither is a wrong choice. The S510 is slimmer and more classically English in feel; the HW100 is a little more Germanic, dense, precise, unbreakable. Our full Air Arms S510 vs Weihrauch HW100 comparison covers the head-to-head in detail, and if you’re weighing up Weihrauch’s spring-powered alternatives instead, our HW95 and HW99S review and HW97K review are worth a read.

Buying a second-hand HW100 in the UK
Here’s the good news for used buyers: HW100s are hard to wear out. The search queries flooding into Rightgun.uk, “HW100 second hand”, “HW100 KT laminate used”, “HW100 for sale used”, reflect a market that knows a used example is a smart buy. Prices vary with variant, calibre, condition, and whether a scope or extras are bundled, with laminate KTs and low-round-count examples commanding the strongest money; compare several live listings to gauge the current market before offering.
When inspecting a used HW100, work through the PCP essentials. Check it holds a charge overnight; seal refreshes are routine but should be reflected in price. Cycle the magazine through a full fourteen shots to confirm smooth indexing, and inspect the probe and magazine faces for wear. Look over the cylinder for dents or corrosion and ask when it was last tested; confirm with a chronograph that a legal-limit rifle is genuinely under 12 ft·lb. Finally, the usual checks: stock cracks at the wrist, scope rail condition, and a bore that cleans up bright. A rifle with a service history from a Weihrauch specialist is worth a premium.
Is the HW100 right for you?
If you want a multi-shot PCP that will do hunting, plinking, and club target work for the next twenty years with nothing more than the odd service, the HW100 remains one of the two or three obvious answers in the UK market. Buy the variant that fits you, carbine for the hide, full-length for the range, bullpup for maximum compactness, and it’s very hard to go wrong.
FAQs
How much is a second-hand HW100 in the UK? Used prices vary widely with variant, calibre, condition, and included extras. Laminate KT models and boxed, low-use examples sit at the top of the used market. Check current Rightgun.uk listings for live asking prices rather than relying on out-of-date guides.
Is the Weihrauch HW100 regulated? Yes, the HW100 has been factory-regulated from the start, which is a big part of its shot-to-shot consistency and its strong used values.
Do I need a licence for an HW100? Not for the standard sub-12 ft·lb version in England and Wales if you’re 18 or over; Scotland requires an air weapon certificate, and FAC-rated versions need a firearm certificate anywhere in Great Britain.
Which is better, HW100 KT or KS? Mechanically identical, the choice is purely stock style. The KT’s thumbhole suits deliberate, scoped shooting; the KS sporter is quicker to shoulder. Handle both if you can, and buy the one that fits.
