What is a good muzzle device for a 10.3 that cant be suppressed?

I have a 10.3 Pistol. I can't own Suppressors in my state. What's the best muzzle device for that build? I have an A2, but I was thinking Surefire 3 prong and warden. My goal is the least amount of concussion to the shooter. Or am I just wasting money on a device?
