OK, will y'all please school me on the FTRB issues with the 30sf model. I am looking to get one and just wondering abou this issue. I am reading a lot on the various forums and cannot come to a clear understanding - is it a trigger bar issue? can I just trade out parts it that all? is it more and do I need to send back to Glock if I happen to get one. I have a great price and I think it may be too good to be true!
