Muzzle flip and recoil are realised long after the bullet has gone! Most moderators will reduce both. There are some very good lightweight mods available now which perform as well as the older and much larger models. I'm not convinced that the titanium or alloy ones will stand the test of time due to the nature of the metal though. I have recently gone for the ASE Utra SL5 which is very short and light, but made of stainless steel. They aren't cheap, but will unduobtedy last.
