Actually did the shoot out today. My buddy had the Sig P226 (the one with the anchor) and I had my new CZ75BD 9mm with the Tru-Glo FO/Tritium combination sights. My CZ has had a trigger job from West Coast Gun Works, and I am completely happy with their work.
My friend's Sig seems to have the sights such that the front sight Tritium dot must be higher than the rear sight dots. Otherwise the gun shoots low, even when shooting "combat style" where the front sight dot is placed over the bull's-eye. Once you get the sight picture in your mind with the front sight slightly higher than the two dots of the rear sight, no problem.
The SIG is bigger than the CZ but weighs one ounce less: 35.3 oz for the CZ and 34 oz for the SIG. Despite the SIG being slightly "larger."
Both of us shot the CZ somewhat more accurately than the SIG. Not sure why. My best grouping with the SIG was, however, about the same as my best grouping with the CZ. If I had to spitball here I would say that both guns are similarly accurate.
The CZ felt better balanced to me, perhaps because it is all-steel. This comment is entirely subjective. Both guns are fun to shoot and handle the 9mm round fine.
The SIG is about $400 more than the CZ here in Soviet California. However, my CZ had a $200 sight and trigger job, plus the Tru-Glo sight was around $100, so really the price was within $100 as between the two pistols. The SIG was entirely stock, and it comes stock with very nice Tritium night sights. The CZ phosphorous sights had to go; I don't like them.
Both guns had very nice triggers. My CZ of course had a trigger job from West Coast Gun Works.
Anyway, it was a fun time at the range with these two fine 9mm guns. Me, I'm very happy with my CZ75 BD!
