Hi all. So yeah, like it says I'm considering a Storm Lake barrel for my M&P45 FS. I have the 4.5" barrel model and was toying with putting 5.3" barrel on it. I use the gun mainly for HD/Target work. I'm just up in the air on the porting should I go with the ported barrel or non ported. I admittedly don't know much about barrel porting. What are the pros and cons?
