CZ 52 Feeding Problem
Does anyone have any experience with troubleshooting a CZ 52 which only loads cartridge about half way to chamber? I examined pistol and notice nothing unusual. Could a weak recoil spring be the problem? It jams up frequently. Appreciate any experienced advice in curing my problem. Just bought the pistol.

billysim47......I have four CZ52's, shoot them often, and have never had this problem. Perhaps it could be the ammo you are using. The 52 is a robust pistol that fires a rather powerful round and usually handles just about anything well including the "hot" Czech stuff, 1600fps or so. But it sounds that the problem is perhaps underpowered ammo. Who did you buy it from? Did he fire it? What was his experience? Now my 52's came from the first batches imported into the US years ago and I have heard that the older ones seem to have better quality than the newer ones. But, if me, I would look at the ammo first and try different loads to run the problem down. If it is a recoil springs they are available from Sarco and others. Hope this helps! Good luck! 0 -
Hi Gary, and thanks. My friend bought Polish ammo in the sealed metal containers of 1260 rounds from Sovereign Guns of North Carolina. They never jam in his CZ-52. My CZ-52 I received one week ago and have fired about 25 rounds and having about 7 jams upon feeding new cartridge into chamber. They make it about half way in and stop there. I can hit the rear of receiver to cause it to complete closing. I notice the recoil spring is not spiraled consistent, especially not when compressed while disassembling. I wonder if a weak recoil spring may be the cause of the problem where it does not close consistently. 0 -
Gary... I bought the CZ-52 from 9311bargains on Gunbroker and received last week. He said he had purchased several for resale. It looks like it has been arsenal refurbished as it is a black bluing. The ammo I fired is Polish with 54 stamped into the brass. 0 -
billysim47....hummm. A couple of things come to mind. First, IMHO Poland makes some of the best ammo and weapons on the market today, so I doubt that it is the ammo. Second, look at the top of your CZ52 and you should see (perhaps) some very small dots. If yours has no dots that means that it has never been through the rearsenal process. One dot, one time, two dots...you get the picture. The most I have seen on a 52 is three dots. Most of the first guns that were imported into the US years ago had no dots which means that many just came from storage and were never issued! They were the best. Of my four, I have two no dots and two one dots. As I have mentioned, neither has given me one minutes problem and I usually fire the cheaper, dirter Chinese stuff! You can also tell the older CZ's from the newer by the color..the older ones have more of a phosphate finish...the newer ones look a bit shiny. and have the "black bluing" that you describe. Anyway, without seeing it, it sounds to me that you have a newer one that has seen some life and probably needs to have its springs renewed. I would doubt that it is the Polish ammo so I am with you on the spring idea. While you are at it, you might think about getting a couple of extra firing pins as some of my friends have also had a bit of a problem breaking them, although that has not been my experience. But once you get her running, you have, IMHO, one fine pistol that while butt ugly, is fun to shot and ammo is still relatively inexpensive! Hope this helps. Good shooting! 0 -
Hi Gary. Thanks for sharing your knowledge with me. I did not know about dots on top signifying arsenal refurbished. This pistol has 3 different marks on top as I will describe each to you. The 1st dot is very small, about the size of a small needle, located direct center about two inches back from the front sight. The 2nd dot is bigger, about the size tip of ball point pen cartridge, but directly in the rear sight frontal groove. Actually it may have a practical application for sighting. The 3rd dot is the biggest, drilled just to the right of the aiming rail and almost two inches forward of the rear sight. The hole does not go through the receiver but looks deep enough to go about half way. According to your description, I bet this is the dot you refer to as signifying one arsenal refurbished. Correct? I notice that as I draw back on the receiver to compress the recoil spring which surrounds the barrell that the spirals on the recoil spring become even more disheveled. I think my jamming problem stems from the lack of strength in the recoil spring. As far as you know, do those recoil springs get weak from shooting many times, or from a barrell getting hot? Thanks for your advice, Gary. Billysim47 0 -
Bill...yes, you are right about the very small dot just back from the front sight on the CZ52. With one dot, your pistol has been through the arsenal at least one time which, as I mentioned, two of mine have also. But it sounds to me as you are on top of the real problem, that being a weak recoil spring. Various distributors have them in stock but I would start with Sarco. As I mentioned, they used to sell a complete Czech armour's box full of CZ52 parts for $160 so they should be able to help you with the spring. I would get several along with a couple of firing pins. Anyway, once you get her running she will be a hoot to shoot. It never fails that when I go to the range and start firing mine someone comes over to see what in the world is making that noise! She is one powerful little beast! Years ago I got some of the very hot Czech stuff to run through it and it got everyone's attention at the range with a foot long flash out of the barrel! The 52 is a stong pistol, with its recoil system engineered by the Czech's much like the system in the German MG42 so it can take some stress. But, like anything else with springs, they can wear out, and it sounds as if you have the problem correctly identified. Glad we could be of help and good shooting! 0 -
Gary.. Thank you very much for sharing your knowledge and advice. Do you think I would be asking Tom Welsh too much to send a recoil spring to replace the weak spring? I bought the pistol from him, he has about 2641 transactions on Gunbroker. He had never fired this pistol. It was still in the cardboard box as he had bought four CZ-52's for resale, apparently from the importer.
Sincerely,

Bill....if it was me, sure, I would ask the vendor to help me out. Just good customer service and it keeps a customer happy plus the springs are not that much $. With that kind of GB feedback rating he will most probably work with you. Glad we could be of help to you. Good shooting with that CZ52! 0 -
Very good thread here, gents.
These are an Xtremely underrated/sleeper-type rig, & I never regretted buying my twice-rebuilt specimen in the early '90s.
Re springs: if the GB vendor falls-thru, ya'll might try Wolff. They offer a tune-up pack (which incl every native spring) for a very reasonable price (spares never hurt). Re Firing pins: J&G sales in Prescott, AZ has them, amongst others.
If funds allow, perhaps scrounge-around for one of those out-of-print 9x19mm conversion barrels. Picked one up on fleabay for about orig retail, & the native Czech mags work just fine there. Only caveat: these bbls were prone to broken rollers, so I made-up some spares from tool steel & so far: we're OK - haven't even needed them yet.0 -
Thanks Guys. Happy shooting to both of you.
