SIG 228.
Although, I'm really warming up to a buddy's CZ-PO1 and am about ready to pick one up ... I also like the two-tone CZ-75 Compact (sans rail).
For the record, I've had a Glock 19, just couldn't find the love ...
Appreciated the S&W 6906, but the ergos just didn't work for me ...
I find the SIG's ergonomics (grip angle, feel of the grips/texture, bore axis) greatly superior to the Glock 19's; it seems to be much more manageable as far a recoil (which is minimal anyway in both platforms) and the sights are much better. The SIG (in my experience) is far more accurate.
The 6906 to me just felt slightly clunky, did not like the trigger pull (the SIG 228, of all I've mentioned, had the best DA pull and a good SA pull).
My buddy's PO1 doesn't have a great DA pull, but the SA pull is respectable, and the accuracy was better than I expected. The big thing though, was the general "feel" of the pistol, which was excellent. Perfect grip angel, well-balanced, good handling, easy shooting pistol.
