With any semi-auto the "chamber case head support" is critical. The chamber must support the case fully, to the point the only part out of the chamber is solid, thick brass. This barrel has excellent support, with the entire case in the chamber, save that one little sliver which is solid as well.
I have seen some Glock barrels, even factory ones, that I'd personally consider dangerous! They probably fed fantastic but if that weak part of the case is exposed at minimum a "bulge" will manifest, at worse a case head rupture could occur, and hot gasses blast out. The KY State Police had some G21's with trouble.
