not heard of any aftermarket companies making conversion barrels for the Pt101 . Looked on the Taurus site and it only talks about the 22 lr kits for a the 92's .
I know sig / glock its just a matter of swapping out the barrel , but it has to be a conversion barrel , made to compensate for the difference on the feed ramps and
extractor from what I read . I spent 100 bucks on a 9mm barrel that fits the G 33 or the G 27 and now I can shoot 9mm thru them and I've not had 1 hiccup yet .
