To me this is a no brainer, pay the extra $25 for a 4 groove. A bargain at that price
Well now, you've left out the most important part of the answer to my original question...WHY?
Why is it a no brainer to pay the extra $25 for the 4-groove barrel versus the 3-groove?
[EDIT: I should add, this is coming from a guy who is kind of inclined to do so - I just want to be smart about it and not do dumb stuff for no good reason]
Thanks!
