I just received my new P-07 and upon initial inspection and cleaning I noticed the muzzle end of the slide goes up and down maybe 1/32".
No slop side-to-side, just vertical. The barrel is tight in the bushing, but the whole slide moves up and down at muzzle end.
All my other CZ's are metal frame with a tight fit. I can't imagine this P-07 being accurate with that much vertical slide movement.
Thought I'd ask 'the Crowd' before contacting CZ. I know there are metal 'tangs' cast into the polymer frame; can these be adjusted??

If the gap is similar to what you see in the picture it is normal. Haven't seen a P-Series gun that didn't have the vertical play.
The metal guns have full length slide rails, on the P-Series guns there is no contact point for the slide up front.

Yep perfectly normal. My P-07 came out of the box that way and is supremely accurate. More than 5k rnds later it's still the same.

Thanks for the images and reassuring responses. Yes it's similar to the muzzle gap that I have. And it goes up and down considerably.
Of course the barrel is parallel to slide and centered securely by the front bushing. Sighting is along the slide; so I guess as the gun is fired and if it stays pushed upward it's AOK. But I have to say there's a lot more slop than my HK VP-9.
Can the guide tabs be adjusted to reduce the vertical play?
-
Just shoot it, I'd bet it groups tighter than the HK.

Yeah, You guys are probably right. As long as when I shoot it moves consistently all the way up or all the way down it probably doesn't matter.
Although I like the VP-9 I'm weeding out my strikers in favor of DA/SA, and I wanted the P-07 for a dedicated Optics gun. So before I send the slide off to CZCustom for milling; I guess I should just go to the range and see what she does.

P-07 ,, there's nothing not to like. After putting in a few cgw Springs and did the polishing, OMG
I had a Springfield XD mod 2 9 mm about six months ,then I saw a picture of the po7 , love at first sight. I sold the Springfield and bought the CZ.
I liked my P07 so much I got the PO 9 and love that even more it's now my EDC.
After I got it, :) I started thinking with carrying an extra magazine I've got 39 rounds of ammo.oh ya

If I like the P-07 with the milled slide and DP Pro with Leupold's co-witness rear iron' and (if it works) using the P-07's front suppressor sight; I'll ditch my Glock 17 MOS and do the same setup with a P-09 suppressor model with 21 extended mags.
The HK will be my last remaining striker. That my go toward a CZ 97BD. :-\
-
Let us know how she shoots!
-
OK, range update to follow.
Planning to mail the slide out for milling early next week. The real test will be how it shoots with the DP, co-witness, and a comp.
And to be fair, I just compared side-by-side with the HK VP-9 and it also has at least as much vertical play at muzzle end I hadn't noticed before, plus their slide rides over the frame so you don't see the gap. I guess it was handling the threaded barrel end on the P-07 that brought it to my attention.

As long as the barrel locks up in the slide you are gtg. Slide play won't be a factor. P-07 and P-09 are consistently the most mechanically accurate pistols that CZ makes.

This. The slide is just rocking in the rail tab clearance because the close spacing of the rail tabs in the frame. The sight to barrel dimensions are not changing at all, and the slide returns to the same position relative to the frame after each shot anyway. Nothing to be concerned about at all. If there wasn't any clearance, the slide wouldn't cycle.

Thanks for the input Joe. I watched your recent video comparing the New P-10c to P-07 offhand at 25 yards. If I could shoot 1/2 that well Joe I'd be thrilled. My old eyes can barely see the bulls-eye anymore at 25 yards, never mind hit it. So, I guess the P-07 will be AOK and it's my shooting that needs fixing. ::) I'm hoping the milled in DP optics will be a help.

The red dot optics are really, really helpful. I'm rusty shooting open sights after 4 years of bullseye with red dots. I still enjoy shooting open sights and I have to show others how to do it, but a red dot helps when trying to shoot small groups at 50 yards and more.
I've tried open sights at 100 yards and the limitation is definitely how well I can duplicate the sight picture and hold between shots. I've shot 3-1/4" at 100 yards with a red dot on a P-09, but usually 4-6" group size, and about double that with the open sights. On a good day.
These late model automated CNC manufactured, reasonably priced pistols from CZ (and maybe others) are phenomenal. Human eyes and muscle control and mental discipline are the areas where improvements can always be made, day to day, year to year.

I know that my P-07 shoots tighter groups than the multiple HK's I used to have!

Just for kicks, I got out my 10k round P-09 and checked the vertical slide wobble. Here's the result and what I concluded...

So, I'm testing out new video gear, this was a perfect excuse to shoot my third YouTube video of the day! :) :)

Is that condition/gap/movement happening on the p10c too?

Yes. And P-07, etc...

Joe, your video shows slightly less up and down movement compared to my P-07; but as you point out and prove from your accurate shooting (on your video yesterday comparing P-10c to P-07) this movement doesn't affect the gun's accuracy.
My guess is that when the round fires, the forces firmly push the slide and barrel consistently up against the frame tabs as the bullet travels down the barrel. The same way every time.
For comparison I pulled out my SP-01. Even with it's long steel rails there's slight vertical movement although not much. Enough to allow the gun to cycle properly with a bullet energy of almost 400 ft.lbs as it leaves the muzzle.
In summary, I've been assured the P-07 will be more accurate than I am. O0
Thanks Guys. Vinny

I saw on my soon p10c, the gap is slightly larger than the one you shown on the video. Is that normal too? Thank you.

OK, RANGE REPORT: YOU GUYS WERE RIGHT! This gun is very accurate. Way more accurate than I am!
After my 1st trip to range I had to make some adjustments. I changed the grip strap to Medium so it now fills my had snugly. I know the Talon tape I'm awaiting will improve this grip as it has on my other poly guns.I also had to drift the rear sight back to center as it was set left from the factory. Even the test firing pattern from the factory were all left.
The results at my 2nd outing after only 300 rounds were much better; dare I say already as good as my SP-01 and I don't expect the trigger to smooth out until another 500 rounds. My old eyes like the P-07's sight picture better with the P-07's larger suppressor dots.
I'm no Bulls-Eye shooter, but here's 25 rounds shot in Defense shooting mode 5-round bursts each starting with DA at 25 feet I would have kept shooting another mag but I ran out of bullets O0:

I'm thinking you COULD be a bullseye shooter. Glad to hear all is well.
