Are you referring to the CZ P07 or P09 DUTY pistols?
I have one of each. Here is the 411 on my take. My exposure to CZ has been very limited over the years being a .gov worker and mostly using what is issued. I have a friend (Pat D) that is FT LEO, trains specialized teams and is a sponsored competitor. Whenever we get together to work drills he used a CZ. And he shot it extremely well. So I always wondered about them, but focused on the issued 1911, glock and M&P platforms. Last year I was shooting with John McPhee and noticed that he had a polymer framed rail pistol that was cocked and locked like a 1911, in nine-milly-vanilly caliber. I asked about it and he handed me a P-09 to shoot for a few reps during the day.
The fact that it was a polymer frame, rail gun, 9mm with a M1911 style safety had me intrigued. My pappy had a M1911 that i plinked as a wee pup and I cut my teeth in the academy with one. I always seem to shoot my best with a 1911. I contacted the LE/MIL sales rep and ordered a P07 and P09. I have been running both of them for a year in an evaluation phase, one or two days at a range doesn't cut it for me. Here is my take on why I like the CZ DUTY series and where they need improvement.
The pistol arrives in the box in a DA/SA configuration, metal 3 dot sights and metal magazines (P09 Full size is a 19 rounder). Each pistol comes with a conversion kit to swap the DA/SA decocker to a SA only safety. I had to search the web to find a video of how to do the swap as the manual didn't quite spell it out enough for me to get it right. Field striping is simple, much like other polymer framed pistols in duty service across the globe. I shoot a lot of drills on a shot timer at multiple distances on standard 8x10 copy paper. I am able to get accurate and fast hits on the paper with the P series CZ's. The CZ shoot with very flat recoil. I believe it is due to the design of the slide being encompassed by the lower receiver frame rails. The trigger feels a lot like shooting a HK USP or SW M&P pistol as far as longer reset that Glocks or 1911's. Eventually I may upgrade to a short reset kit to get the feel i prefer, but I wanted to spend about a year playing with the CZ in a stock configuration.
The magazines are metal magazines which i prefer over polymer magazines just for overall reliability during reloads, durability, etc. The cheapest price i have found for magazines is from CZcustom for about $42 bones a piece. Yup, the mags are a bit pricey. I can fit the CZ mags in an existing Blade-tech M&P 9/40 pouch on the belt. Holsters are bit of a problem. I run the CZ's in the Safariland universal holster, I think it is the 560 or 568. I wish Safariland would make an ALS with x-300 holster for these pistols and I think the P07 and P09 could make it into the LE market.
I have not experienced one reliability issue with either the P07 or P09 to date. I would guesstimate between the two i have about 6K rounds through them. So it is a baseline metric on reliability, but not a standard as of yet. Overall based on other end users feedback and my short time on the DUTY models I think it has a possible future as a reliable, hard use out of the box gun.
