Any tiny holes in a suppressor are to alleviate pressure which could otherwise blow it apart, adapter off your muzzle or help with turbulence not affecting the projectile.
I believe every DonnyFL has 1/32” holes in front retainer cap & at back. This really doesn’t have any discernible effect on decibels heard by anyone in area. I actually ported my Tanto’s holes to 1/16” and noticed a huge improvement as it’s on a Condor that sends everything over the 800 fps recommendation limit of Tanto.
I have a simple baffled carbon fiber LDC on my Sumatra and I had to put a 3/8” plastic washer between it & muzzle. The POI is now very close to not having it on at all and it does an excellent job at quieting down the beast neighbors thought was a .22LR or .410. He shoots his .40 & AR’s quite a bit. He just thought I’d switched from air to powder but I told him no, just need a can as it’s not a plinker.
If you won it congratulations.
