According to Tom Gaylords blog on February 17, they are no longer being made. From what I’ve read, you couldn’t get parts for them even while Sig was still making them. And they have a plastic trigger. I’m spoiled by the triggers on my Weihrauchs.
This is what I feared.
However, to answer the question about accuracy, my .177asp20 comes VERRY close to my hw97 under 50 yards. It was a harder gun for me to learn to shoot well, but I am comparing a break barrel to a world class under lever that is dramatically less powered. I have many groups where my asp outperforms my 97, but on a whole the 97 is more accurate.
The lagging area is the trigger. It is no rekord, but the matchlight sig trigger is a very well purpose-built trigger perfect for a hunter. It is not a plastic trigger, but a metal trigger covered with a polycarbonate sleeve from my understanding. The fit and finish for me are perfect for a hunting gun that you don't mind to ding up a little while hunting.
