Not sure if this is where to post this topic, but I wanted to warn others about my experience with ETS. Their Glock magazines looked pretty appealing at $15 each. But these do not last. The quality of the sprigs causes them to need to be replaced very frequently (3 times in 18 mos). They also have some feeding issues in my PCC.
the saying “buy once cry once” definitely applies here. Hopefully this thread will keep someone from having the frustration I did.
