I just received my new 9mm conversion barrel for my G27 today that I purchased off forum member texas48. My wife and I went to the range and put 150 rounds through it today without any malfunctions at all. I haven't changed the ejector or the extractor although I had planed to, now I don't know if I will or not. I think I will pull them out of my 17L just to see how it will function with the 9mm parts. The 27 was very soft shooting in 9mm. I do need to get some mags as I was using my full sized mags out of the 17L. I really like the conversion.
