I will be pasting my reply to the "CZ or Beretta..." question in a moment as I think it is relevant here as well. But first, a few specific CZ v. SIG thoughts.
Both are high quality guns which will probably never let you down. Both are well made, good looking (IMHO), reliable, accurate, etc.
Which is more accurate? I don't know, I've never shot a CZ in .40 or a SIG in 9mm. My 9mm CZ 75 is the most accurate 9mm I've ever shot. The SIG 239 that I got to shoot was the most accurate .40 I've ever shot. I'd be very interested to shoot a comprable 9mm SIG back to back with my CZ. I'd guess there would be very little difference.
Better workmanship? For the most part they are comprable. From a purely cosmetic standpoint, CZ doesn't put forth quite as much effort on making the internals look as nice (still look good, just not as good as the exterior of the CZ or the interior of a SIG).
Quality, reliability, durability. I doubt if there is any difference. I won't repeat what I say in the pasted message so you will see what I have to say below.
I love my CZ and I will buy more soon. I will eventually buy a SIG or two. If I had unlimited money and had neither, I'd get the CZ first. It is as good a gun as any. It is currently very inexensive. One of these days CZ is going to realize what they could ask for these guns and prices will go up 50-100%.
The pasted message follows:
I think in any CZ or... question I'd have to say go with the CZ, regardless of the second gun in the question. If you want something else after you have the CZ fine, but get a CZ!
I did a lot of research here and at the
CZ forum before I got mine and they have a great reputation. I've only had mine for a month but I'd say the reputation is more than deserved.
It is very reliable- I have only had one minor hiccup in 1300 rounds, and that was when I let the oil on the rails go completely dry. It is my most accurate gun. It is highly durable, it was designed as a military gun so it was made to take a beating. The exterior fit and finish is incredible, the interior fit and finish is good. I find that it fits my hands very well. Some 9mm models are still available from the factory with high-cap mags (the BD Police and the Mil). Also, the factory made up a ton of 9mm high-caps just before the ban so there are plenty on the market and at good prices (you can still order them from the factory for $48 and some sources are less). Both the "polymer" finish and the nickel finish are highly durable finishes. In my opinion the gun equals SIG for quality and workmanship. You get all that for a gun that costs the same as (or less than) a Ruger or Taurus auto.
