I returned to air guns in 2016 after break since the 80's, so all the new stuff about was amazing. I tried & purchased everything, but now sold it all & got back to springers.
Like the OP i'm left handed, & now own a 2nd hand 97kt in 22 that has been stage 3 tuned had a Ti piston & pellet probe fitted by Paul Short. But my current love is a left hand tx200hc in 22, that i paid less for than the tuning to my 97kt.

There are lefty tx's out there, but the 97kt i have is nice.
