Haven't received the 30274 ejector that I ordered 2 days ago, so took the Gen 3 19, TTL***, to the range with the load bearing / spring, safety plunger / spring, extractor from my 2005 G17.
After 100 rounds, 50 Blazer aluminum and 50 Win NATO, I had no BTF and all cases ejected to the right. Next is to add the original load bearing / spring back. I think it's the original non-dipped extractor causing BTF's. Testing will tell.
