New P?07 Failure to Eject Every Round

[CAK]

Wow, CAK!

I took the slide off my P-07 and saw that it has hardly any wear marks on the ejector compared to yours--which has obviously had some friction on it.

My ejector has only two very small wear marks on front and back, but it is still black finished in the middle.

Yours looks like its been touched with a dremel, but I guess we know that somehow your slide has put the wear on it. At least it's not giving you any trouble. And whatever real resistance you had has been worn off.

It's just polished on the surface, hardly the thickness of the black finish. No gouging to the ejector itself.

Colorado Shooter: The huge scrape/wear marks on the ejector are not normal for a new P-07--or any P-07. There's not supposed to be any friction in that area.

There is something wrong with this P-07. Perhaps the ejector got bent so that it now touches the inside of the slide. But it is not supposed to.

having seen 100s of P-07s I can tell you for sure that some extractor wear is extremely common and evident in most P-07's.  It will not impede function in any manner.  The OP should really send his firearm to CZ to have them repair it, but if he does not want to the best bet would be to buy the newish black recoil spring from cz-usa or could use one of the lower powered ones available from aftermarket sources like cajun gunworks.

Well, OK! CAK had already pointed that out, so I guess I cede the point that some friction btwn the slide and the ejector is to be expected.

But his gun is not ejecting completely.

My P07 has similar wear marks to CAK's.  I had problems with FTEs when I first bought the pistol, so much so that I created a thread about it on this board. After I put some +p rounds through it, no problem.  With factory new ammo I have never had a problem since that time, through 2-3k rounds and almost a full year of shooting IDPA. However, I bought some Freedom munitions 115gn reloads and my pistol  FTEs like its going out of style with that stuff.

I'm glad that there's not that much of a rub btwn ejector and slide on my P-07. I wonder if there isn't some kind of fix for that?

But before you guys go trying to bend your ejector on a pistol that is still working pretty good, we probably need to hear from CZ or some expert on this .

Anyway, don't do anything that might cost you before someone knowledgable tells us about it.

Maybe just polish the left side of the ejector. That would reduce any friction there is and surely wouldn't weaken or re-position the ejector. Couldn't hurt anything to try. but you would have to be careful to just polish it and not grind or file off too much.

my new P-O7 stove pipes some 115gr Tennessee cartridge reloads. has been cleaned, just order's the 15&18RS also the 97040 Compact SSGR from CGW. Thanks for posting up folks will give feed back after I get put in.

Took my new 07 to the range this morning, absolutely no problems with ejection or anything else.

The owners manual recommends oil not grease..  The viscosity of the grease may be slowing the slide speed enough to cause your problem.

I had the same problem with my P-07 but not my P-09, a lot of FTE's with lighter ammo.

Put the 15 pound recoil spring in tonight and only fired one mag, but it ran great with the same ammo.

I have the same wear mark on my ejector.  I wouldn't worry about it but that is just my opinion.

OP Update:

So I ordered the lower powered 15 pound gold recoil spring from Cajun Gun Works. At first I ordered a captured recoil spring assembly from SSguiderods.com but found It difficult to take apart so I sent it back and went for the non-captured Cajun Gun Works guide rod

The experienced failure to eject problem did in fact appear to result from an overpowered recoil spring. My first mag I only had one failure to eject and the slide failed to lock back. I continued to experience one failure to eject for the next additional two magazines.I noticed the ejection of the spent brass was extremely weak - Only about 1 foot to the side of the pistol. I then realized that the front Cocking serrations were beginning to rub my left support hand thumb raw. So I moved my support hand thumb downward to where it only contacted with the frame. After I adjusted my grip in this manner the pistol do not have any further failures. Spent brass shot further out of the pistol.

I also gave two rounds of my 124 gr Fiocchi ammunition to the gentlemen in the stall next to me shooting his Glock 17. The ejection was also weak coming out of the G17. Possibly I got a weak batch of ammo but this was definitely the first time I've had any problems with it I'm nearing the bottom of the case.

rocketfish: I also had the same weak ejection problem with my Glock 17. So it probably wasn't weak ammo causing the problem. Whenever I shot Federal Aluminum, I had some of the empties hitting my shoulder. I put in an aftermarket ejector with an adjustable overtravel for the trigger and now the Glock 17 is working great and throwing the brass out where it is supposed to go.

Never thought I would have a pistol that outshoots my modified Glock 17 until I got the P-07. Now it is my favorite.

This might be super obvious to some of the more experienced tinkerers out there, but when I spoke to a person at CZ he told me that every pistol has its individual parts' tolerances stacked just a little differently, and once all the tiny things add up the same recoil spring strength is  going to work fine for some guns and just plain suck for others.  Glad some people are having luck with aftermarket lighter springs, as I'm wanting to do the same thing

I happened to stumble onto this thread searching for P-07 ejector issues. I recently purchased a 2nd generation P-07, cleaned/lubed it and took it out to the range. When I came home to clean it I noticed that my ejector had a rub mark where the ejector and the slide rubbed during the initial shoot. Actually I think mine is worse than any of the pictures I've seen on this thread. There is an actual gouge/groove cut into mine from the slide. It almost appears as if the ejector wasn't bent quite right. I can feel the interference when I rack the slide. However, I didn't seem to experience and ejection issues so far.

I will try to post a picture once I figure out how.

I did send CZ an email on it to hear their thoughts. Rocket fish, have you resolved your issue?

Any thoughts?

Thanks!

Not trying to ask a dumb question but could the extractor spring be missing? Commercial manufacturing can occasionally miss a piece part. I can't tell from your photos.

The ejector "rub" is normal.  Nothing to worry about.  Lastly, these pistols are sprung for SAAMI standard 9mm operationing pressure of 33,000 CUP (Copper Units of Pressure). 

Most USA 9mm bulk is "target grade".   How do you think they can make bulk ammo cheaper?  Easy, with a reduced powder charge.  Most of this target ammo is running around 30,000 CUP or less.

So you have to match the recoil spring to the pressure of the load.
