Are you bagging on Army Armament mock-Glocks from personal experience?
My AA R17 has been fine for maybe 1,000 rounds, using its own mag or WE mags. If that doesn't sound like much, I'd suggest counting how many pistol shots you actually go through in a day.
Paying TM or even WE prices for a woodland hip-hanger has never made sense to me, and my R17 has been fine as a CQB primary. If and when it fails, I'm minded to just buy another (and end up with loads of spares) than sink money into it or pay more for another brand which might fail out of the box.
