So I'm looking at the storm lake ported barrel and I'm not sure if it's worth it or not. Is there a significant difference between a non ported barrel and a 2 port or 4 port barrel? Notice I said significant and not "huge" or "massive" because I just want something practical. I've considered KKM but they do not make ported barrels for G21's. I've also noticed Lone Wolf but read some rather undesirable stuff about the feeding chamber (No disrespect to lone wolf owners.) Again I'm not looking to shoot the thing and have the gun line itself up for me and feed me some grapes I just want to tame it a little. More importantly I would like a little tighter ground too. From what I hear and what I've researched Storm Lake Barrels are some of the best.
