I've found threads on this topic with older millennium pistols - but not the newer millennium G2 series. I'm hoping to find a first hand account of compatibility here. I just bought a PT111-G2 and have gone so far as to pop one of my old 24/7 gen one 17rd 9mm mags into it - and it locks in, and cycled the snap caps I ran thru it. But before taking it to the range I was hoping to get confirmation that it works and won't be detrimental to the gun or my face. Thanks!
