Im nowhere close to being a competition shooter, and Ive never fired a non-FPB CZ75. So to me and most shooters like me, it makes little difference. The closest thing that Ive shot would be a Series 70 1911 vs Series 80 1911. I know the 80 has an FPB but I cant really tell a difference in trigger pull.
She (Tamara, Im assuming She) still hasnt given any explanation as to why she feels the way she does about CZ or Sig. In my experiance both are awesome guns. The only real blemish I see against Sig is the P250 line.
Having owned both as well, I agree completely.
At the $1,000ish price point (typical stainless elite price ballpark), the CZ 75 Shadow is a better comparison than a base stainless 75b at about $5-600. My $.02 is that its a better buy than 1k for a stainless elite as well.
