    I got myself a SP01 for christmas and I loaded up the magazines this afternoon to see how difficult it would be to get them fully loaded (misplaced my speedloader). However, after I put in 6 or more rounds the magazine started to rattle. They rattled when totally full as well. One rattled a little more than the other. I took them apart to make sure they were assembled properly and they were. Google search turned up that this is a common thing. None the less, I find it annoying. Is there any way to fix this?


    Side note: I bought some snap caps to get used to the DA/SA trigger and I must say that I find my SR9c's trigger amazing when I did a comparison. With the CZ I'd get a fair amount of "perfect" to pretty good trigger squeezes, but with my SR9c my sights didn't move at all when squeezing the trigger (a lot better than I can do with a glock). Just thought that was interesting.

    Can't help you on the mag rattle, but the trigger will never be outstanding without some hammer work. As you pull the trigger in SA mode, you will notice the hammer moving back at the same time, and unless you alter the positive angle on the hammer hooks to a neutral or less positive angle, it will always be long and gritty. The gritty will wear in with shooting, the creep will still be there. Did you get a manual safety, or decock model? The manual safety guns are alot easier to work on if you like to tinker, plus a lighter mainspring will greatly improove the DA and SA pull of the trigger. Enjoy your new CZ, they are shooters for sure!:)

    Actually I just got a 75compact that has a decent trigger which was a pleasant surprise. I changed the hammer spring and I put in a different firing pin safety I had that was slightly polished on the sides. Other than the usual camming of the hammer the trigger is very clean. The camming isn't gritty either. Before I got the compact I checked out a 75b at the local gun store and the trigger on it plain sucked. I just got a good one. Mark

    I got a CZ83 ~ Super gun in every aspect. One thing I have noticed is that if the mags are full (12 rounds) they rattle, one less (11 rounds) and they don't. Either way is not an issue since, I don't usually go around shaking my gun.

    My gun has a decocker and no manual safety. I planned on putting a new hammer spring in and a competition hammer later. The trigger isn't too bad right now. I was worried it would be horrid, but I'm pleasantly surprised. That said, this is my first DA/SA gun so I don't know what's good or bad. It seems decent though.

    Any idea why the magazine would rattle? Sometimes I can get it to stop by slapping the mag a little if it isn't full, but there is no stopping the rattle if it is topped off.

    A good slap on the backside of the mag will stop the rattle on my 75
    compact without decocker

    i just bought a compact about two months ago and one of my mags does the same thing. i have no idea why but it functions ok. i was not too worried about it becuse mine came with 10rd mags so i am going to replace them with the 14 rounders with the baseplate. i will say that these mags are not cheap $49.99 & $29.99 with flat metal baseplate. but with those my little finger has no wear to rest.

    If slapping the mags back side into your hand to set the rounds and see if that helps with the rattle. If it does not there is a trick that helps the owners of the KT p-11's. Double stacks also. They also rattle and the fix is to use some rubber and a pair of channel locks or a hammer to tap in on the sides of the mag. It works but you can go to far. I let mine rattle. Only does it when the mags in my hand or atleast i can't hear it once it in a holder or in the pistol. Check out KTOG forums tech section for the fix. Different pistol, same problem.

    Do the mec gar mags for the cz 75b rattle? They're 17 rounds and the SP01 takes them. The ones I saw have a blue follower and were on midwayusa.com. I would lose a round (mags that came with it are 18 rounds) but I wouldn't be sweating it.

    Mine do....but its a range gun, and I had to load them just now to check.....thats how much I care;)

    If its a carry gun, it would drive me nuts, but not if its just my range shooter.

    This condition is common to many double-column (actually not true double column as they taper to a single column at the top, but close enough) pistol magazines. You may find they rattle with an odd (9, 11, 13 and so on) number of rounds loaded but not with an even number (8, 10, 12 and so on), or vice versa. Furthermore, it will usually stop when you insert the mag against a closed slide, thus putting pressure on the top round. It may be a little dismaying and surprising at first, but it doesn't hurt anything. No one else is going to hear it.

    My 75B is well over 20K rds and I never noticed a rattle. I just tried it with 10 rds in and there was 1 hard shake that produced 1 small rattle, tried again and no rattle.
    I'm curious what bullet-type are you loaded with? If it's a flat nose or hollow point, they have to be loaded to a much shorter OAL Maybe that extra space in the mag gives the cartridges some room to move. I've recently replaced my mag springs , so mine's tight.

    re the trigger: Being new, your SPO1 probably doesn't have 500+ trigger pulls on it yet. The trigger components will "seat" after enough trigger pulls and smooth out quite a bit.
    Reducing the hammer spring/mainspring to 15# makes a very noticeable improvement to trigger pull and still reliably fires all primers.

    It rattled with fmj. I loaded it up some HST to 17 rounds, chambered a round, then put in another round to get it back to 17 and smacked it a little and the rattling stopped.

    Only other issue i had was when popping rounds out of the magazine. Some of them didn't want to pop up all the way, but I'm guessing thats just from slowly pushing them out, and that the round will rise to the top of the feed lips when cycling during firing. Problem hasn't occurred when cycling snap caps.

    All my mags do that as well. I use a pair of them like maracas and dance to a Latin beat to upset the guy at the line at my IPSC matches..... :D

    Since anything you do to "fix" this issue would involve messing around with the mag's shell or follower I'd suggest that it's best to just accept this peculiarity. And it's not just CZ mags that do this. My factory Beretta 92 mags do it as well.

    Carter: Let me say re "feed", the mags should work flawlessly when clean & 'dry'/unlubed in any way.

    Because I tend to be anal, and run very light springs (including recoil spring) in my gun, I've found one way that makes mags very slippery and they don't pick up 'any' dirt from combat mag drops.

    I wax them inside and out with a quality car wax. I use Meguiars liquid Gold. Others work fine too. It actually makes them 'very' slippery and bullet feed is smooth with minimum force and using Xtra power mag springs.
