Advice for misbehaving CZ 97B

[lone shooter]

So I took my 97B out to the range for the first time over the weekend. Loaded up my two OEM magazines with some Fiocchi ammo and began to fire away. Pretty much immediately I started to have problems. Every second to third round failed to load into the chamber. Pulling back the slide I could see the round sort of stick at the bottom of the feed ramp. To remedy it, I would either pull the slide back a few times consecutively or drop the magazine.

Unfortunately, I only had the Fiocchi ammo with me at the time so I could not try to isolate the problem down to the ammo, the magazines or the gun itself.

Anyway, I continued that way for away and managed to fire about 100 rounds before giving up. But also during this time the screws securing the wooden grips became loose and I had to tighten them. It was one thing after another or so it seemed. Unlike my 75B SP-01 that has run flawlessly from day one.

Hoping to make another range trip with an assortment of ammo this time. Hope I get better results.

generally CZs don't like weak ammo. I haven't shot Fiocchi out of mine, but WWB, Sig, perfecta and Fed seems fine w/ my copy.

My grip screws come loose too on the first outting, seem every couple months I have to tighten down one side.

OEM 10rd or OEM standard cap and blocked to 10rd?
Other than not having enough lube or shooting weak ammo I cannot get my CZ to FTF like that. OEM 10 rd and pre 2k OEM standard cap mags.
Tried to swap mags with sp01?

I've heard Fiocchi ammo is a hit or miss. I would definitely try a different ammo. I have several 97's and none of them has ever had any FTF or problems. They are awesome guns.

OEM 10 round magazines.

No swapping between the 97B and SP01 magazines. Right now I'll say it's the ammo but hope to try others soon,

Did the slide lock back on the last round?

After reading your post again, I need to know if your 97B was purchased new or used. Is it bone stock or semi-modified?

I bought a used Tanfoglio Witness Elite Match 9mm which I thought was stock. I had failure to feeds every 2-3 shots too. People told me it was weak ammo, bad magazine or weak recoil spring. Turned out that the original owner swapped out the recoil spring to a lighter weight because he used reloads. I changed out the recoil spring back to the original weight and all is fine now.

I would look into recoil spring first. Don't be surprised when people come in and say your limp wristing.

New and unmodified.

FeuerFrei - I believe the 10-rd CZ 97B mags are the standard mags for the gun, so there is no "blocked" mag. And the CZ 97B is .45 ACP while the SP01 is a 9mm so there is no swapping of mags...

Anyways, to the OP, maybe try some hotter ammo first, or other ammo for that matter. Try to eliminate that first since your gun is brand new and unmodified. Also, are you certain that you are not accidentally activating the slide stop when shooting, especially upon recoil?

[Litespeeds]

Just strange that even his grip screws came loose. What is the manufacture date of your 97B?

Hey Op sorry to hear that you are having issues.

You stated that your "Wood" grips were coming loose. Are these stock wood grips? As i understand it the older model CZ97 came with wood grips.

It may very well be the ammo if it is not pictures of the pistol and the feed ramp would defiantly help.

As far as the grips screws go, mine loosened up as well with the aluminum thin grips. You can fix this by adding some tiny O ring or some blue locktight. I switched to the CZ97 rubber grips and it solved the issue for me.

I would bring a few different types of ammo and see if it happens with all of them. If the problem continues CZ's customer service/warranty process is very easy and quick.

I had those same problems when I had my cz97b. The grip screws on the older grips just don't bite and will always work their way loose unless you put a small o-ring on them. Mine would have clambering issues too like the ops. Do some research to see if you have the old style feed ramp and I think cz will switch out to the new style for free. Not positive though. I ended up selling mine right when they updated the feed ramp and I'm kinda pissed at myself now.

You are correct on both counts.
