I bought a BG 380 when they first came out in the EAA series and although never shot it was concerned about the problems. I did field strip it and clean it however. I got rid of it and now have a late SN# EAF series.
I noticed how easy the takedown pin came out on the EAA and how stubborn and difficult it was to remove on the EAF. Wonder if that was part of the fix. Also saw a You tube clip commenting how difficult the pin was to remove on the recent releases. Sounds like progress and a good thing. Also like the new ring around the laser buttons.
