Just got ahold on a brand new S2K and I was curious if anyone has a comparison between the Tacticool Recoil buffer insert vs. the MCARBO recoil buffer insert. They look completely different in design and function, they also look to b made out of 2 different materials. So that makes me wonder if one does a better job of reducing felt recoil then the other? I know it’s only a 9mm but that heavy bolt slapping that hard plastic factory buffer can’t feel great. I haven’t shot it yet but I’m going to the range this Sunday and will make my decision to buy a reducer or not but if I choose to reduce then my next choice is, which brand do I go with. Yes, I am over thinking it but I am bored at the moment and was curious if anyone has experience with both buffers?
