Leshiy .357/9mm

Anyone here have some experience shooting the 9mm Leshiy? What moderator did you use or modify? Doesn't seem to many people are posting about the 9mm Leshiy barrel but Edgun West sold out a little while ago. I've only seen one video about it and EDgun Leshiy videos shooting squirrels. Trying to get some info on setups for shooting the 9mm out of this small gun.
 
I use a drilled out Donny FL extended baffle with two extensions to contain the bark a little.

With the Huma reg set to 150 bar and the hst at 27 clicks the speed with the 81 grain JSB is 203mps / 666fps.

At this power level the Leshiy bucks like a mule but is manageable from a heavy sandbag, when I do my part it groups under a MOA at 100 meters.
