Finally got a chance to take the CZ83 to the range to see how it feeds Federal HSTs, but on the first shot, the magazine fell out under recoil! I double checked seating, and it won't pull out, the fired again, Same thing, it popped out, My fingers are not near the mag release so it has to be mechanical.
I'm thinking Weak catch spring or worn catch. I have never had this happen. with prior 82s or 83s I have had, and I have never heard of it either. Any guidance from the Hive?
