yeagger - maybe some further detail when you say "I had a Huben K1 and It did not like me I think." in your original post.
I recently (last Friday) received an 04/2021 production K1. I've only had it out for maybe 4 shooting sessions, but I am getting to grips with it pretty well.
FOR ME-
1) I am one who shoots a traditionally stocked rifle accurately more easily than a bullpup like the Huben;
2) The semi-auto action of the Huben makes it even a bit more difficult for me to shoot consistently/accurately as it has somewhat of a bi-directional recoil like a springer;
3) My K1 has operated flawlessly through the 500 or so pellets I have put through it so far;
4) Although Kelly at KRAZ Cool says that they seem to like heavier pellets best, mine was more accurate at longer ranges (I have 61 yards in my back yard)
for me with the 25.39 pellets than with the 33.95 pellets (mine is a .25). I guess because of less recoil & muzzle flip - pushing a lighter pellet, and with the gun set at a lower power level.
5) I don't think that my K1 will ever become my go-to rifle for long distance accuracy work (although it probably has that potential in the hands of a better shooter than me), but after a short time with it my 61 yard 5-shot groups are at least down into the 0.8-0.9" range, with many fewer flyers than I was originally having with it.
For me a SA air gun is a bit of a novelty. I may find that I eventually use it at the range to deal with some of the ground squirrels who are trying to destroy our safety berms. But currently that role is being addressed with an Impact Compact, so the K1 has some pretty big shoes to fill.
So maybe let us know a little more about your less-than-stellar experience with the K1, and maybe a little more on how you intend to use your upcoming SA air rifle purchase.
