Overseas we work in security with SOF groups and we mostly carry glock 19s with 17 round mags. We don’t need a longer slide (our max engagement distance is 50-100 yards with handguns) but we do need more ammo. This weapon was designed for that, but glock decided to release it to civilians. Which is why I own it to EDC.I fail to see the advantages of the 19X that make it so special. Is it just me?
