CZP07 - hammer spring and plug replacement

[gdtrfb]

new to forums and just would like a bit of info.   Bought a new P07 a few weeks ago.  Was waivering between a basic glock gen5 19 and the P07.  I rolled the dice and got the P07.
 I cleaned and lubed the firearm before each outing including when initially brought home.  FTL issues with magtech 115, 124 both FMJ;  S&B 115 and 124 both fmj, remington defender 124 JHP.    The only ammo that did not fail to load through a 50 rnd box was Winchester nato 124.   About 350 rounds through thusfar.   I wanted to change up the backstrap to getting a better grip.  Finger that covered the plug/hammer spring slipped when pulling the pin out.   1.5 hours later with flashlights looking over every inch of the floor, no parts found.  Seems like CGW has springs, but you have to change out other parts.  I am not interested in swapping out tons of parts and investing money in it  My main reservation and hesitancy for a CZ was in the parts realm, and based on searching for a bit, it was substantiated.

In all honesty, I am not very fond of the pistol.  Shoots fine, but it just isn't that fun.  I am fine with DA triggers and shot both of my revolvers in DA all the time for practice.  Reliability is a massive concern given the failure to load.   This was no tap rack... resolution,  it took effort to get the cartridge out., and if I have to spend all kinds of $ on replacement parts and upgrades, I would have gone with a different option.  This was a total leap of faith trying without firing.  Totally regret trading in a GP100 to subsequently buy this new.  Very much wish I would have bought a honda civic (glock) instead.  I am not a collector and don't want several firearms.  I enjoy my 22 target pistols and just want a single self defense, camping, home gun.  What is the best source to get parts so I can make this functional and just move on to something else?

cgw is taking backorder requests for the plug, the spring is tbd?   cz parts does not have the 'parts'. cz custom does not list them

First, if it's new you can call/e-mail CZ USA and they'll e-mail you a return authorization form/barcode label to print up and ship it back to them so they can take a look at it and fix it for you.

FMJ failing to load?  Do you mean it hung up/stopped somewhere between the magazine and chamber or it went into the chamber but not fully and the slide wasn't closing all the way so you could fire the pistol?

Slide no closing all the way and then you having a hard time getting the round out of the chamber sounds like the bullet it jamming into the metal/lands of the barrel.  That shouldn't happen with FMJ ammo or most hollow points.

Have you done a plunk test to see if the bullet it hitting the lands/leade at the end of the chamber and stopping the bullet from completely entering the chamber?  You can find explanations of the plunk test here on the forum or look at different videos on you tube that show you how to do a plunk test.

If it fails the plunk test take a picture of the rim/base sticking up above the back of the barrel tab and sent that, with the info on the ammo used, to CZ when you e-mail them.

Win. 124 grain FMJ NATO ammo is "hot."  In the area of +P ammo.  Nothing wrong with that, I use it in some of my M&P pistols which seem to need it to shoot the kind of groups I'd like them to shoot.  The difference between it and the other FMJ ammo you listed is power, pressure, recoil, etc.  So, back to the thing about failing to load.  The other ammo is weaker and may not be working the action with the same force as the Winchester NATO ammo.  You might try locking the slide to the rear and sitting it on a shelf for a week or so.  Same thing works with magazines.  Fully load them, let them sit for a week or two and they'll seem easier to load after that.

Doesn't help you any but the P07 can be an awesome pistol.  Zero issues with mine in the last 11 or 12 years of concealed carry.

If you can't diagnose/fix the problems give CZ USA a chance to fix it for you.  Or buy a Glock.  I bought one maybe 15 years ago.  It's been in the safe for maybe 14 years.  I just can't put up with a handgun that shoots patterns instead of groups.

new to forums and just would like a bit of info.   

Welcome from Georgia.

Please take a few moments to familiarize yourself with all the sticky posts in the 'New Members' section. Together with the Help Topics in the 'Important Information' or 'FAQ' sub-section, these include 'how tos' such as 'how to' post pictures on the forum.

I cleaned and lubed the firearm before each outing including when initially brought home.  FTL issues with Magtech 115, 124 both FMJ;  S&B 115 and 124 both fmj, Remington defender 124 JHP.  The only ammo that did not fail to load through a 50 rnd box was Winchester NATO 124.  About 350 rounds through thus far. 

The statement above makes it sound as if you think 1) all 9mm gun chambers are cut the same, and 2) that all 9mm ammo is made to the same physical size dimensions. They are NOT ! The P07 has ammunition constraints, just like the Gen5 Glock 19. Not the same, but similar.

Please start your research on ammunition in our Directory of Ammo Buying Information: https://czfirearms.us/index.php?topic=114236.0

Others can address the parts availability.

Again, welcome.

Mcarbo has full spring kits but that probably isnt for you. Wolff has individual springs for sale for the P07. fwiw, you mention a FTL (failure to load) but also mention an extraction issue. i have used all of the ammo you listed (all in 124gr) and blazer, winchester, federal, and fiocchi in115 with zero failures in 2 P07s. never had any issues with parts availability for CZ from Cajun, Mcarbo, Wolff and Primary Machine. 350 rounds should be broken in for a CZ, imho. if you continue to have issues i would consider sending back to CZ for a warranty look.

Greetings, and welcome to the forum from gUNfriendly NJ !
   Odds are, after this initiation to CZ ownership, you are not going to become a big fan of the P07; but I'd at least encourage you to have the factory try to straighten things out. Even if you decide to go with the Glock, you can sell sell it as an operational pistol by factory standards. 
    I bought a P07 online that almost got sent back before I even took it home from the FFLs shop. DA felt like crunchy peanut butter, and SA was hard. Some improvement after 500 rds and better after 1000, but it was accurate and no malfunctions. Took it apart, polished the innards, and now I absolutely love it ! 
    All the know-how and encouragement I needed was supplied by the good folks here in this forum  ! I sure am glad I was patient and persistent. I've got over 5000 rds through this pistol, and suspect it will see many more to come !

Your problems with several different ammunition brands suggests a the problem isn't a chamber length or bullet nose contour problem and should be pretty easy to fix.  working with the short slide height and stiff slide stop release my be complicating your problem.
Suggest following:
- find lost parts - they are too large to really disappear.   
- note where the cartridges a hanging up.  gives readers a better idea of how to help you
- remove slide and check the magazine is fully seating and the top cartridge is setting just under the ejector nose.  means that
  cartridge is positioned ok and ready to feed and not too low when hitting feed ramp.
- release slide using slide stop lever to chamber cartridge. stout recoil spring release means that you aren't manually releasing slide to
  slowly if you sling shot slide release.
- look for a gouge in the face of the barrel feed ramp that is catching bullet nose.
- come back to forum with results

Hope he comes back to read the posts trying to help him.  He hasn't been back since the 19th, when he posted his one and only post.

I suspect, after rereading his initial info, that NATO ammo is providing enough slide velocity to eject the cartridge and the recoil spring rebounds quickly and has enough energy to strip the next cartridge of the magazine and push it into place in the chamber vs std pressure ammo doesn't.  New gun but assume problem exists with both magazines.  First fix would be to relax the magazine and recoil spring and see the effect with std pressure ammo - might not have to get into more involved trouble shooting.

found the parts, and will give it two more range sessions with an open mind before making any decision to ditch it.  Niche stuff just isn't for me in general.  one incongruous aspect of firearms is the lack of capability out of the box.  Regardless of manufacturer.   Putting in good trigger parts cost literally NOTHING out of the gate.  Why not charge 25$ more and just make it decent ootb trigger?   This goes for ruger, smith, glock, cz.....  Seems completely substandard, and nothing something we put up with other mechanical devices.  Yes.an aftermarket short shift kit for a track day car feels more precise and better, but the stock shifters generally don't suck enough to go that route unless it will be really used on the track.  When they wear out, going with an aftermarket upgrade makes sense.

I have 3 P07s and 2 P09s never a hitch out of any of them.
