Sig all the way
...
First, I love the "get a 1911" crowd.. loyalty carved in stone, and a legend in the archives of mans achievements in gun design..
But for those of us that, both, want a DA/SA triggered, with "Manual hammer cocking" options, as not to carry with a cocked hammer, then we talk about the CZ vs Sig.
From my personal experience it came down to a few main issues.
Weight and balance (which includes weight of gun in CCW mode all day)
Draw and point-balance, ease, natural feel, with extended lengths of time in a holding point and aim mode.
Ease or unease of slide action, and manual hammer cock.
And do I need, or want, a safety mode.
The winner of all these issues was, and is, Sig for me.
The most important feature that really highlighted all the above issues was, and is, the fact, that Sigs "decock only" feature, and the "placement of the decock lever-design" of it for easy, non-fail, no-brainer (no need to think how or where) to use it with my left thumb "while maintaining" a balanced, 2 hand grip, being able to tone-down a controlled situation back to DA mode, from SA mode.
And, unlike my Beretta, where I lose the "good 2 hand grip" to use its decocker, and even though its decocker works, every time, it still lets the hammer hit hard with that loud click, even though the rear exposed firing pin moves UP and I know it cannot (in theory and its design) fail, it might, it could, but I always grit my teeth when I use it, as compared to Sigs, perfect location and their 2 stage release platform, being its soft, quiet, effortless, use, while the hammer stays recessed from the firing pin, as you see it when it is in DA mode.
Sigs 220 is my next gun without doubt and for the above reasons, along with my Sig 229 9mm's continued, perfect, 850 rounds thus far, with no FTF's nor jams.
CZ's are FINE guns, make no mistake, but it should always come down to: in the eye and HAND, of the be-Holder.
