Yeah, the Dynatex .209 all come with one hole at the top.
The SWAT VTG came with one at the top and 4 larger ones around the side because it could also take a 12 gauge blanks. (It came with 9mm and .209 adaptors)
I didn't need to make the extra holes in the VTG but I had the drill out and I was in 'Driller Killer' mode 😆
(They were properly measured out so nice and symmetrical)
True the .209s don't have that much power but its possible it could land next to someone prone to get it right in the face so I don't want to take any chances.
I also have the SWAT VTG that takes the 12gauge but I'm not going to use them as I wouldn't want one going off next to me
9mm is as high as I'll go. The .209s are actually plenty loud enough and less than 10p a throw.
