9mm Compensator for 4” barrel

[Darkblast]

Anyone have recommendations for a compensator for a B&T GHM9C? I have to get a muzzle device pinned/welded for state compliance. I was thinking of something with vertical ports to minimize side blast. My main concern is muzzle flash blinding the view of the red dot.
 

Looking at something like this:

Or just pinning a thread protector.

Just curious-as short as this weapon is, what requirement will be met with one of these muzzle devices?  To qualify as a "pistol" the barrel has to be less than 16 inches and to qualify as a rifle, over 16 inches...

He might not be from the US, so the NFA doesn't really apply to him, I live in Argentina and here most of the PCC shooters have MPXs with 8 inch barrels in "pistol" form but with a stock, yeah, it's still a pistol, don't ask me how that makes sense.

 

I would recommend something with bigger side ports:

I also wouldn't worry about the muzzle blast interfering with your red dot, I mean, we're still talking regular handloads barely above power factor, right ?
