I know this forum is focused mainly on rifle accuracy, but I'm gonna change it up a bit 
I'm in need of an accurate semiautomatic pistol. Budget is about $2k...
I do not own a 1911 (yet), so I've been eyeballing a couple STI models. However, when I was at the range the other day, a guy was shooting a CZ 75 SP-01 that was "accurrized" by the CZ Custom Shop. It's essentially the exact same thing that CZ sells as the "Accu-Shadow". He was nice enough to let me handle the pistol, and also fire a couple of rounds out of it. My first thought was "OMG, why is this the first I've heard of this pistol." It's one of the nicest, and most accurate semiauto' s I've ever handled, and now I'm thinking about ditching the 1911 idea.
Now, I have ZERO experience with custom 1911's, so I can't really compare how this CZ felt in my hand, compared to an STI, or the like. So, the point of this post, is to get some feedback from anyone with experience with the CZ platform and the 1911 platform. Are there any reasons I wouldn't want to pick up a CZ?
To keep the conversation off of caliber selection, assume 9mm in both platforms.
