Well I mailed it off yesterday, to fix a premature slide lock, mag dropping problem while shooting and stripped grip screw bushing which fell out. I guess we will see what happens.
-
Sorry to hear of your problems. My PSL problem was solved with the new[beefier] slide lock spring sent to me. I haven't experienced PSL since, and that's been about 300+rnds or so.
I have never heard the mag drop problem on here before, doesn't sound very common. Were you messing with the grips prior to the bushing falling out? I have been thinking of putting on custom grips but haven't decided yes or no yet. Well, good luck with it and I hope they attend to you faster then they did me.
-
I bought some grips from Omega and when taking the factory grips off the bushings came out with the screws on one side of the frame. I tried to put them back on but it screws throught the frame to far and interferes with the mag. I am not a gunsmith so i figuered I would let the fix it, I hope
. The mag problem I believe is mag related. I have a Z40 made for Colt and the mag does not drop during a shooting string. I don't think I am accidently hitting the release. I guess I will see what CZ says.
-
I too experienced the premature slide lock once as I was shooting a box of fifty rounds. I will contact CZ about this, although I had assumed that perhaps I shoved it upwards with my thumbs whilest shooting....
You know, all that nice fancy grip technique...

I got my CZ back today it took about 3 weeks. The work order stated that installed a new slide stop spring, recut the mag catch and replaced the magazines. I will find out thursday if that fixed my issues. The grip bushing were also repaired. Very happy with the pretty speedy repairs just wish shipping had been cheaper.
-
Well, CZ fixed the mag dropping issue and out of 150 rounds fired the mag did not drop once except when the release was pressed. The accuracy was great however the slide lock issue is still occuring. CZ did replace the slide lock spring while they had the gun.
While shooting winchester white box it occured 3 or 4 times per 10 round mag. I switched to hollow points and it decreased to about 1 per 15 rounds or so fired.
I will be calling CZ again for a replacment slide lock spring. Anyone know if there is an aftermarket source for a stronger spring?
-
I don't think there is a stronger spring available, The factory one is made from pretty stout wire, but if you put some slight bends in the one you have you might be able to get it to put more pressure on the slide stop.
-
I've put approx. 1k rnds thru mine since replacing the slide lock spring, and only once did it occur in that time. My friend was firing it, but I'm not sure if that was a factor. I also polished the feedramp, you might want to try that as well since you said changing ammo altered the results. I changed the recoil spring and mag springs as well, trying to fix the problem in addition to the brass ejecting 20-25' from where I fired[it didn't
]. I am glad to be in the position of giving advice rather then needing it in this case, as it was quite frustrating when it was happening to me, so I sympathize with you. Good luck and keep it pointed downrange.
-
Premature slide lock is most-often due to weak mag springs (which allow the top round to move around and nudge the slide stop.)
I've had p-m slide lock in several guns, only once was it due to the slide stop spring itself. Mag springs -- extra strenght from Wolfe -- generally fix the problem.
-
Well count this as TWICE then since replacing the slide lock spring fixed it for me.
I replaced the recoil spring in an effort to fix the far ejecting brass problem[it didn't] and was replacing the mag springs to hopefully fix the premature slide lock problem[it didn't]. Generally speaking, different guns with similar problems have different fixes, generally. If he is speaking of the 40B[which I have] then I would say replacing the slide lock spring should work for the psl problem, unless they put in a standard spring as opposed to the beefier one like I got in the mail. I concur with Jeff and maybe xtra bend in the spring would help.
-
Well, I went to the range today and ran 90 rounds of CCI 180grn FMJ through the gun and had only one premature slide lock. Which is great. I had another problem while shooting however. I started to notice that the baseplate on the mag was moving around alot. I looked at it and noted that the base plate on the right side of the mag had sheered off. I will try and get a replacment for it but I think I am going to trade this pistol off this coming weekend,
Anyone need some Omega Purpleheart grips? $40 shipped only mounted once.
-
Sheered off? on the bottom of the mag?? WTF are you doing to "sheer off" the bottom of a mag[if that's where it is, if not it's not the baseplate], and how is this the guns' fault to get rid of it?
-
It's not the fault of the gun. I have just descided I don't want to mess with it anymore. The baseplate sheered off where the slot that the mag base slips into to lock it in place. I'll post a pic if you want to see it. I think you need to relax a little. I guess I should not have even bothered to post on this board, it has like what two members in the cz40b section?
-
I was curious and counted about 12 different members posting in the 40B section in the last month, not counting you since you are getting rid of yours. Actually, not bad numbers considering the 40B is not as common as the 75b or 97b etc. Are you going to sell your 40b on gunbroker? If so, post pics with it so I can see the sheered off part. Sorry if you think I need to calm down, but your post sounded more like an abuse issue then saying you were getting rid of it cause you had enuff of it.

here's mine with Hakans Desert Ironwood grips. I love it.

Here is a pic to illistrate what I am talking about. I do not abuse or misuse my weapons they are well maintained but do see use. This mag in brand new by the way and came back with the gun from CZ. They replaced the original mags that I sent in with it.

Not only does it look "sheered off" but cocked at an angle as well. Almost as if it were used to pry at something, like the slide release for disassembly perhaps. I sure hope my mags don't just spontaneously sheer off for no reason.
-
I'm sure it looks cocked only because the rear tabs are broken off and the front parts are the only thing holding it in place against the spring pressure.
I've had to replace the baseplates on all my 40B mags with metal ones. I used it for IDPA a couple times and all 4 baseplates cracked from being dropped during reloads. The plastic can be a bit brittle and the rear edge of the baseplate angling out like that is bad design for a situation where the mag will be dropped on the ground.
-
As I said these mags were brand new this was there first range visit and the gun had not even been stripped after it was received from CZ. I wanted to see if they fixed it. The baseplate is cheap plastic crap. I don't really care if anyone believes me or not, but don't imply that I am a lier I thought other owners of this pistol might want to know about possible problems they might have to deal with. I'll end this thread now...................
-
I don't think anyone was attacking your honesty. (Gunrfunz can be a little "direct" sometimes, but I don't think that he was trying to say you weren't telling the truth.)
Sounds like a defective baseplate in the example shown. As noted above, those plastic base plates can break if they hit just wrong on a hard surface.
Standard CZ mags will work fine. They will just leave a gap at the bottom. (You can get standard baseplates from CZ.) I'm sure they'll replace the bad one shown under warranty.
40Bs are among the least troublesome of all CZs. Sorry to hear you've had problems.
-
I sold it at the gunshow today for $280 cash and bought a 5 inch Ruger 22lr Mark iii. I am not mad about his post but it sounded like an acuzation to me. Maybe I was taking it a little to serious. Enjoy your CZ pistols and happy shooting.............
-
It did not happen to be sold at the C&E Gun show in Mechanicsville, VA did it? I bought one, used, at this gun show! I only got one factory magazine. The pistol was in very good condition. I took it apart when I got it home and it was very clean inside and out!
Sorry to hear about your magazine base plate failure! I have to wait until after Christmas to actually fire my new baby! My wife says that it is my Christmas present!
Yours,
Bob T.

I sold mine in Pasadena, Texas at a small gunshow. Enjoy your pistol you will like it I think. I just had some bad luck with mine and did not want to spend money on it to get it where I wanted it.
Need some grips I have a nice set of Purple Heart wood grips for sale $40 shipped
