Yes really. The stock Glock chamber is excellent for feeding just about any kind of crap imaginable and still staying reliable, however because of the generous chamber dimensions I have found my 10mm brass was getting bulged severely, admittedly using Very Hot loads. Once I started using a KKM barrel this was no longer an issue. I realize Glocks have their place but I like my STI Edge WAY more and look forward to having a second barrel in 10mm made for it.
