ruger is a good company and I like MADE in USA stamped on all the stuff I buy but their DA/SA semi's aren't very good, their striker guns are much better.
IIRC correctly all these guns are made in the US except the CZ.
The Beretta is made in MD. The FN is made in SC. The Sig is made in NH. The Ruger is made in CT.
FNs best gun is not DA/SA it is the Browning Hi Power which is a SAO gun. The FNPs are decent guns and were a steal when they were $300 guns but these day at $450 they are not "deal" anymore. The DA/SA on these compared to a the Sig Pro is mushy. IHMO
The Sig is cheaper than most of the guns on the list with the exception of the Ruger. It only comes with one mag which is a stike against it. It has a long but smooth DA pull but the SA is quick and smooth. It is overly large for it capacity but it makes sense because it was designed as a duty gun for the French police who plan on using it until 2022.
Ruger is built like a tank and looks like someone worked it over with the ugly stick twice.
They work but man they look like hell and the grips feels like a 2"x4". I would take one if you gave it to me but I would not pay for one.
The CZ P07 is a poly version of the P01/Compact/PCR and had some issues when it was first released. They have worked through those but they will like all CZs exhibit some amount of camming and the DA will be stiff OTB but gets better overtime. I personally prefer the P01 to this poly step brother.
I have no experience with the Beretta so no coment.
All these guns are within $150 of each other. It really comes down to ergos which are subjective. Which one works best for the person doing the shooting. There is no right or wrong choice.
Once again tahunua001 you need to check some of your facts... and take your own signatures advice. LOL
