Best to contact Hatsan direct - they have a good english website where you will find the slug/chokeable barrel combos. But, as Ryan surmised, they may not be compatable, even if you DO find a barrel for sale. Best to check.
MJ - if you DO track a replacement barrel, and it looks like it will fit, and you can remember this thread, lol...PM me, wouldja?
I'll do the same for y'all...cheers.
I took mine to a skeet shoot, much to the delight/horror of the old Colonels and their $5000 O/U's.
I actually managed to get 2/20 (lol)- but only after I discovered the key was Yell "pull" and blast about 10 feet in front of the thrower a split second later, lol...
I just wanted to fire my new shotgun. I told them don't even bother with the clays, just tell me when it's my turn, and I'll do a mag dump in the general direction - but the ole Colonels were having none of it!
;-)
Take care bud...
