According reviews the .25 has a choked barrel, not the best for slugs. Anyone who tried a custom unchoked barrel?
Hello Harold, the new "2020" version of the .25 is due for release* this month, it may have (and I am hoping) a more slug friendly barrel.
As for "custom", the only one I am aware of, and I have ask this question before, was Gregor Kamensek, He put a LW in his, but reported Limited success.
* Kelly at Krazcool (US),is reporting stock as of mid July.
As yet I cannot find a dealership in Europe that is going to stock the new .25.
Good luck.
Harold I Found what I was looking for.

Hello. I have been shooting my K1 .25 quite a bit actually. I have a poly unchoked barrel in it. The reason why I haven't made any video yet is because I don't get very good results with slugs. I even made a new slug but I am still not happy with the results. The poly barrel is shooting with pellets extremely well though..
