I am back into 1911's and Highpower's these days. Have 11 1911's and 3 Highpowers.
I am down to only 4 SIG's.
I agree with Skeeter as I believe the 228 is simply the best of all the SIG's, and that makes it simply the "best".
And for goodness sake, don't get lost in the caliber wars. Any of those calibers you mentioned, 9,40,357, or 45 with good modern ammunition will do anything that a pistol can do. It's about software, not the hardware. Just make sure what ever you get is stone reliable. Hence the SIG 228.
Get the SIG. Then pick and choose your 1911 carefully. Remember if it ain't a Colt, it's only a copy. But I ain't prejudice.
Good luck.
