LIO, I have an idea that you want a double rifle for use on dangerous game like lion, buffalo, and elephant. If that is the case then I would not buy a Blaser S-2!
Accuracy is very good in most double rifles if the proper load is used. Looks is not a factor in the usefulness of a double rifle but the S-2 is about the ugliest double rifle I've ever seen, but that is a personal thing.
There are a couple of things that, IMO, make the Blaser unstable for use on dangerous game. First off the so-called safety system is, in this case, anything but safe. Let me explain! The system "IS" safe as a loaded rifle can be when placed on the safe (de-cocked) position. So far this system is the same as the Krieghoff rifle, but that is as far as it goes in that comparison.
The K-Gun can be carried loaded exactly the same as the S-2, and when the switch is pushed forward the rifles both are cocked and ready to fire. That is where these two rifles part company.
Now let's do a hypothtical!
Your walk in on a cape buffalo and he charges from 25 yds! You fire the right barrel, then the left, the buff is still on his feet, and continues on to take you on. Now you break the rifle re-load one or both chambers slam the rifle closed and fire three and four on the closeing buff. If you are shooting the K-gun then that is the way it will be.
However if you were fireing the S-2 Blaser you had better not have forgetton to re-cock the action or you will not fire the rifle again, because that rifle automaticlly de-cocks the rifle when opened for any reason. That is a feature I certainly do not want on a double rifle I'm useing to stop a mad buffalo. The auto safety makes no sense at all on any rifle used to hunt dangerous game. It makes no more sense on a double rifle than it does on a bolt rifle. I don't think anyone would want an auto safety that re-set the safety every time he worked the bolt!
The K-gun, once cocked, and fired, re-cocks it's self when opened for the re-load just like all hammerless double rifles, and is ready to fire as soon as the rifle is closed. To place the rifle back on safe if the rifle is not fired again, simply push the switch (safety button) forward slightly , and release, and it is de-cocked and safe again.
The other thing on the S-2 that is a potential problem is the hooded barrel breach, making it difficult to remove a stuck case if the extractor doesn't pull it out enough so it falls from the chamber.
You may use what ever you want, as long as you are willing to live, or die for that decision! I will not reccomend the Blaser S-2 to anyone who hunts anything more dangerous that a whitetail deer.
