SIGs and CZs are my favorite pistolas...have both guns and it's a tough call!
First, regarding quality, reliability and accuracy, both are dead EQUAL!
Both guns are 25-30 years old and are the 'flagship' guns for both companies (the .45 P220 is also one for SIG).
Personally, the
CZ 75B fits better and is the 'sleeker' of the two (for me) and would be my
FIRST CHOICE... you can't beat CZs ergonomics (for me, NOTHING beats their
P-01!!!) The P226 seems a bit bulkier... both BOTH are dead-on accurate!!
You really have to hold 'em both and shoot 'em both to make the decision that's right for YOU.
Also, the CZ 75B comes in both
Manual Safety and the
Decocker models. I have one of each but prefer the decocker in all my guns. The P226, comes in decocker only.
Also,
price is a factor if money/budget is a concern. A CZ 75B can be had NIB for about
$475... a SIG P226 NIB is about
$750... that's almost a
$300 difference and for ME, the SIG is definitely NOT $300 more gun. My
75B Stainless is one of the smoothest shoots I own... and a great target-gun!!
For my
CCW/HD choice... it's neither. I go with a
CZ P-01 and
SIG P229 (both smaller).
Good luck... you won't go wrong with either choice!!
