10-11k on my SRO still with no issues.
My Type 2 RMR Is back at Trijicon again getting another battery terminal replaced, it did still work with the single one though. That’s twice in a year.
I was pretty sure it wasn’t the springs. There’s something wrong with the G2 grip/mag release combo on some of the guns. I knew this when I bought mine and was fully prepared to swap to a G1 grip but mine works fine.
