The KS variant of the HW100 is the one with a Sporter stock, this stock made from finest walnut and then oiled. It has checkering on the fore end and pistol grip and a nice sharp comb on the stock. The SK has a carbine length barrel, this barrel is 10cm shorter than the S and this can be a real benefit when moving around woodland. It also makes the rifle more compact and this helps shooters keep stable when they are taking both standing and kneeling shots.
The HW100 is probably the finest all round PCP (Pre-Charged Pneumatic) on the market today. It is the darling of the target shooting world with multiple national level shooters using them. It is also found in the hands of the best hunters and plinkers alike. Target shooters love the HW100 because of its reliability and accuracy and hunters love it because of the multi-shot magazine system, high shot count and usability.
The HW100 is a regulated rifle (Weihrauch call it an air metering system) and has a fully adjustable trigger and legendary build quality. The HW100 is often described as the only Air-Rifle you will ever need.
