So I, too, was experiencing ejection issues with target load ammo. I have a recently born Gen 3 with 1000 rounds through it (TTL***). Consistently, with Federal 115 grain FMJ, I was getting 1-2 BTFs every 10 rounds or so. So, with the information found here, I replaced my ejector. I found my extractor to be the non dip type (which seemed to have have less reports of issues). So I replaced my 336 ejector with a 30274. I ordered the Gen 4 trigger housing from Lone Wolf Distributors and swapped out the ejector from it. (The Gen 4 trigger housing is not compatible with the Gen 3) Today, I took it for a 100 rounds of test fire and received not 1 BTF. In fact, the ejection was the most consistent I have seen it. Obviously, many more rounds will be necessary to call the problem completely solved, but I thought I would share my findings for any of the rest of you folks dealing with this. I will say that while I was previously getting BTFs I never had a complete FTE. Good luck to all establishing your Glock's perfection!
