I sent my Gen 4 G17 in to Glock on 3/7 for FTE's and brass to the forehead.It is a December 2010 manufacture date. I got it back this week. Got the paper from Glock stating what was done: Inspected Upgraded Meets Factory Specs Tested ok. It looks as though they installed the new 30274 ejector. Not sure what else they did. I really wish they would include a bit more detail like what they did, how many test rounds were fired. I mean what do they consider "factory specs". I will test fire this weekend to see if its fixed.
