I'm going to be the only naysayer. I've put a lot of time in with both a Beretta and a Girsan over the past 7 months. While I like my Girsan just fine, my inclination would be to buy a used Beretta off the EE rather than buy a NEW Girsan, especially if I wanted a full size. With a Beretta I can be absolutely 100% sure replacement parts will fit without some minor tweak needed. The only reason I bought a Girsan was that I could not find a centurion length Beretta.
That being said, I think the vast majority of shooters would be reasonably happy with either brand. Most shooters don't shoot their guns enough to have to worry about parts wearing out or breaking.
