I fired 200 rounds of Turkish manufacture ZQ1 9x19 FMJ ammunition this morning, and experienced six blown primers, as well as some of the cartridges "feeling" hotter than others (not a fan of wonky and inconsistent ammo). On one occasion, a blown primer induced a malfunction in my FNS (FTEX).
While not the end of the world, I'm going to stick to CCI Blazer Aluminum and my reloads for no drama practice ammunition. If you see this stuff on sale at your local Wally-World, there's probably a reason.
Caveat Emptor.
