The guns CZ makes are purpose built guns, the Shadow 2 was built for production class and it rules the class. If I remember right, production class doesn't allow half cock, hence no decocker.
I have multiple guns built from CGW, safety and decocker, sitting down and dry firing, you can barely feel the difference. At the range doing drills, I can't tell.
CZ pistols really shine on the Pre B and Shadow line because they lack a firing pin block. My Pre Bs and Shadow2 with worked over triggers would make the vast number of 1911s blush.
In SA the trigger has less than 1mm of slack than breaks at 2.5lb with a quick short reset.
The da on my shadow 2 is right around 5.5 lb and smoooooth.
The SA only guns,CZ, once again different division.
The SA version of the Shadow 2 is not very popular and costs the same as the regular shadow. The SA of the regular cz75 is discontinued.
The Beretta 92x was built as a gamer gun to take on the Shadow 2.
Having both a shadow 2 and 92x performance, I'll take the CZ.
