Sorry I don't know anyone that runs a Beretta or Sig. Even Slavex moved to CZ from Beretta. Sigs don't fit everyone hands, the DA normally makes you have to change grip to reach. Also it written like AI. CZ Shadow got good recoil management because they lower the bore axis.
Sig I found had the most flip, as they got the tallest slide and top heavy.
Glock, SA XDM or CZ 75 Shadow or Shadow 2 would be the choices Id choose.
Esp if you are limited in club matches.
I started with Glocks and 1911s, then moved to CZ.
Dad started with Sig, then switch to XD and back to Glock.
If I knew what I knew now. 20 years ago, Id started with CZ. Spent alot of money trying to find the best.
