The other way to look at it is this. The majority of confrontations end with either no shots fired at all, or one or two fired. Is it worth it to you to go from 7 to 8 rounds when the vast majority of confrontations will only take less than 2? If it is, then buy the product. If not, then don't, simple as that.
BTW, I carry a SR9c with 11 Hornady CD on tap, so take my opinion for what it is worth. Stay safe out there!
