Verdict (short):
If you need a suppressor that barely affects rifle balance, shaves grams off long approaches and still handles full-power .300 Win Mag shots, the Svemko Pure S is an outstanding pick. It’s absurdly light for what it can take, built for long climbs and demanding stalks and, in the alpine conditions I hunted in, it gave me the mobility and confidence I needed.
Specs at a glance (from Svemko)
- Build length: 135 mm · Total length: 180 mm · Outer diameter: 42 mm.

Short intro & context
I took the Pure S to Tajikistan on a mountain hunt for giant wild boar. My rifle for the trip was a SAKO 90 Quest (carbon stock) chambered in .300 Winchester Magnum. The trip demanded long approaches, heavy daily packs and the ability to drop the pack and stalk light; that set the decision criteria: keep weight low, keep quality high, and control recoil on a big-bore carbon rifle. The Pure S met those demands.

Why I chose the Pure S over the Pure M
I tested both the Pure S and the Pure M on the range before departure. The Pure M gave a touch more noise reduction on paper (SVEMKO documents the Pure M’s .308 attenuation higher than the S), but it also weighs about 100 g more (Pure M ≈ 298 g vs Pure S ≈ 198 g). On the mountain hunt every gram mattered — we were carrying rifle, day pack, food, water and heavier glassing kit (a Zeiss Gavia spektiv) and frequently hiking steep ground where a lighter, less intrusive can made a practical difference. For situations where I would leave the pack behind and stalk with rifle only, the Pure S’s minimal weight and compact profile won out.
Handling, balance and recoil on the SAKO 90 Quest (.300 Win Mag)
Handling, balance and recoil on the SAKO 90 Quest (.300 Win Mag) Mounting the Pure S on my SAKO 90 Quest (carbon stock) changed the handling in a very positive way. The added mass at the muzzle is tiny — the rifle’s balance remained true, which matters a lot when you’re shouldering quickly on narrow ridgelines or holding a steady glass-and-wait posture. This plays a critical role when you wound one of those giant wild boars. Luckily, this was never the case on our trip.Nevertheless, I considered it carefully while building my kit for the hunt — one of many reasons why I paired the rifle with the Zeiss V8 1.8–14x50 scope.
Recoil with the Pure S felt notably reduced compared to an uncapped rifle; muzzle rise was easier to tame and follow-up shots were less disruptive. That recoil mitigation was a key factor: carrying a very light carbon-stock rifle in .300Win Mag is rewarding when the suppressor helps keep it manageable. (Your subjective impressions may vary with stock and bedding, but that was my experience.)
Sound reduction — good, but not the primary mission
Svemko rates the Pure S at roughly 26–29 dBC for .308, which is impressive given the weight and size — and for most hunting situations that translates to a perceptible reduction in report. On the Tajikistan mountain ridges the environment is open and the sound doesn’t tunnel like in cliffs or canyons; I wasn’t primarily concerned about minimizing signature because the acoustic behaviour in those open settings disperses quickly. Instead, I prioritized weight and the practical benefits of felt-recoil reduction and packability. Still: the Pure S’s attenuation is “absolutely fantastic” for such a small can and it leaves a very neat impression on the range and in the field.
Field notes — Tajikistan mountain hunt (real experiences)
Approaches & packability: Our daily loads were heavy — rifle + day pack with food/water + Zeiss Gavia spotting scope and other filming kit - so every gram counted. The Pure S’s sub-200 g weight let me leave my pack behind for rapid stalks without feeling hand-cuffed by a bulky can.
Mobility & stalking: On several stalks I moved light with just the rifle. The slim profile (42 mm diameter) and short length made the rifle much easier to maneuver on tight ridgelines and through scrub. No snagging, no bulky silhouette while climbing or crossing rocky outcrops.
Durability & environment: After long days in dust, grit and cold mornings the Pure S continued to function flawlessly. SVEMKO’s titanium core construction is designed to resist burn-out and corrosion, which gave me confidence that the can could handle multiple magnum shots and the rough conditions. I had no signs of core damage or deformation.
Perception & filming: When we were filming, the Pure S’s look mattered. It doesn’t read as a bulky accessory - on camera it looks sleek and professional. People who handled the can off the rifle were often surprised by how light it felt and by its capability (they initially guessed it belonged to an air-rifle or small-caliber setup). That may seem superficial, but for media projects the aesthetics and perceived professionalism of kit do matter.
Pros & Cons (practical summary)
Pros
- Extremely light for its class (≈198 g) - excellent for long approaches and stalking.
- Titanium core construction - high durability and low burn-out risk.
- Compact profile - minimal effect on balance and handling, looks great on camera.
- Good attenuation for its size - useful in both hunting and range work.
Cons
- Slightly less attenuation than - larger Pure M / Pure L models - trade-off of size/weight vs ultimate noise reduction.
- In narrow canyon/cliff acoustic environments you might prefer a longer/heavier model for maximum dB reduction.
Verdict— who should buy it
Buy the Svemko Pure S if you:
- Hunt in mountainous or mobile scenarios where every gram matters.
- If sound suppression is not your most important feature.
- Use high-power calibres but want to keep rifle handling lively (e.g., carbon-stock magnum rifles).
- If the look of your kit plays a role.
- Want a durable, titanium-core suppressor that can sustain hard use without a heavy weight penalty.
If your priority is absolute maximum sound reduction (and you’re not as weight-sensitive), consider the Pure M or Pure L in the same series - they trade a bit more mass for higher attenuation.
