Not a CZ. An M&P Shield, or Shield Plus is an awesome shooting pistol.
You can get them in OR (optics ready) models, 3.1 or 4" barrels/slides, night sights or no night sights, ported barrels/slides or not, thumb safety (left side only) or no thumb safety.
For me they're starting to be like a small AR15 - buy parts, switch/swap between frames to change calibers, barrel/slide lengths, optics/sights, etc.
My 1.0 9MM (9MM, 8 shots) was a 3.1" barrel with night sights. It now has the 3.1" OR 9MM slide/barrel that came on my Shield Plus. My Shield Plus OR 9MM now has a 4" slide/barrel OR 9MM slide I bought as a stripped slide and built up with parts from several on line vendors.
I've bought a 1.0 3.1" .40 S&W barrel/slide/recoils spring assembly (slide/barrel were used) and magazines that works on my 1.0 Shield 9MM frame. I bought a .357 SIG conversion barrel for the .40 S&W slide that also works on the older Shield frame. I'm experimenting (and have shot it several times at the range) with running the .40 S&W slide/barrel on the Shield Plus frame (required modifications to the Shield Plus 9MM mags.)
It's fun/neat if you're the type that like to work on/with your guns to make them into something you think you'd like to have that the factory doesn't offer.
Sorry, not trying to offend the serious/die hard CZ fans. I still carry my P07 .40 any time I have to get in a vehicle and go somewhere. I just don't have the options to buy/build what I want with CZ's anymore. The P07 fits what I want for EDC. I do know that like any other gun brand/model, not all P07's are identical in accuracy. My Shield is for those times when I feel the need for something quite a bit smaller than the P07.
