If you're going to use it for hunting, you might consider the little Bowers "Bitty".
I have one on a 5.7 Ruger pistol and one on a 17HMR bolt gun. On the 17HMR it knocks just enough off to make it shootable without hearing protection, yet doesn't add a pile of length or weight to the barrel.

Run it up, until you blow it up, then back it down a bit.
