A few quesitons... I'm going to be shooting a lot more reloads/lead this summer than usual. And I've heard it recommended that I replace my stock barrel with a match grade barrel. I've never swapped in a glock (G19) and I know all platforms respond a little differently to barrel inserts. So here are my questions: 1. What does a match grade barrel add to the glock other than better reload shooting? Does it noticeably improve mechanical accuracy? 2. What does a match grade barrel take away from the stock g19? Is it less reliable? Will it really just "plug and play" with no reliability issues? 3. Based upon the benefits/costs, is Lone Wolf good enough, or if I'm going to do it anyway is it worth the extra $70 to go KKM? Thanks.
