in the 7 or 8 1911's I have owned over my lifetime, only two gave me trouble, one was a used Colt 70 series gunsmithed by a knucklehead. I paid him $350 for and I found out why, the second a new Kimber with the wrong spring in it from the factory. The biggest problem with the G19 is that the 9mm rings your ears a few dB's more than a .45ACP. smile , the biggest weakness with the 1911 I guess is that the shells are a bit more for the 45. Push come to shove either one works fine for me.
