Glock has 65% of the LE market, but I think the Sig P320 may make serious inroads. Unfortunately, I've never seen a CZ in an LEO holster, but that doesn't mean they're bad. Many other countries use them extensively. I recently switched from Glock to CZ because I really like the DA/SA, even though I have a lot of experience in shooting and carrying a Glock I never totally trusted the Glock safe-action trigger... I think the CZ 10c is a good choice, as for me it was the CZ P-07...
Here is the thing too, police departments and even government contracts (probably very obvious on this one) don't always pick the "BEST" gun, whatever the definition of best is. However, as a former naval aviator and later contractor in Afghanistan, I worked with SF types, both active and contract, have some good friends in the Teams. They have money and can pick whatever they want when it comes to firearms (though when active, sometimes under the table). Granted, the handgun is a secondary weapon, truly meant to fight your way back to you rifle. The one common gun that is used, seen, in a holster on their person is almost always a Glock. A good reason for it, it is a gun that works. It doesn't anything great but does everything good. Never have I seen a CZ of any time down range....I saw Sigs, XD's with Croatia only, HK, M9's of course and Glocks, many, many Glocks. It is the go to gun.
With that said, I am a fan of CZ's, have owned a few now, including the P07 and P07, the P01 and the CZ 97. All great guns and never a malfunction between them, ever. The P07 was probably my fav of those but they are all gone, replaced with what I think is probably my new favorite polymer handgun, the CZ P10C. Of course it is very Glock like, fits in every one of my Glock holsters. Police departments and maybe military units may move to it, I don't know. I actually now have two CZ P10C's though one is already back at CZ for malfunctioning, it is a new design after all.
I used to say if I was back flying in the military or had an option as a contractor, the G19 would hands down be my gun but as an aviator, if I'm using my handgun, the $hit has hit the fan. The enemy has either come over, through or under the gate, or worse, my aircraft is down. But the P10C might be my choice now, maybe. I think it is an evolved Glock...better ergo's, trigger but keeping in the tradition of a lighter weight in a smaller package. The G19 is amazingly size efficient, its best quality in my opinion. The P10C is slightly larger but doable. Anyway, I won't ever move away from my Glock 17 and 19's, great guns, but I will add to them. Reason I have Sigs, HK, CZ, Walther, etc in my collection. And I do love this P10C, having one on me now, as I go to lunch in an Incog IWB holster made for the G19...fits perfect!
