Bought a 320 compact Thursday and got to the range for the first time this morning. All I can say is Wow! Standing, two-handed rapid fire from 35 feet and I was doing inch and a half groups immediately. (With one or two fliers.)
I had two FTFs in the first mag, but after that totally smooth sailing through another 100 rounds of WWB. Interestingly, I read either in the manual or on the Sig website that, in terms of hold, you ought to cover the bull with the front sight. I started that way and was consistently shooting high. So I changed to six o'clock and was right on.
Anyway, I'm in love. Good-bye Ruger and Beretta.
