chuck s Posted January 4, 2014 Share Posted January 4, 2014 I shot a match today and had two ftf issues while changing mags at slide lock. As best as I could tell, the first bullet in the new mag went in nose slightly up and this jammed against the breech. When I got home I pulled the mag springs out and they seemed really flimsy so I replaced them with new m&p mag springs I had around. They now seem much stronger. Could at have been the issue? Is it common with CZ mags?(75 shadow 9mm, maybe 500 rounds fired) Link to comment Share on other sites More sharing options...
Andreas Posted January 4, 2014 Share Posted January 4, 2014 I had occasional feeding problems until I installed extra-power springs in all my CZ-75 magazines. The stock springs had trouble keeping the rounds firmly planted against the feed lips. Link to comment Share on other sites More sharing options...
Carnifex Posted January 5, 2014 Share Posted January 5, 2014 I put the +10% springs in my sp01 mags. Never had a problem feeding as long as the mag lips weren't totally jacked up. Link to comment Share on other sites More sharing options...
CZinSC Posted January 5, 2014 Share Posted January 5, 2014 Chuck, yep, the stock mag springs on the CZ are horrible. Usually with stock springs you leave bullets on the ground like bread crumbs. In your mag pouch the bullets just start falling out. Not enough tension. Go to either CZCustom and get +10's ore Wolff. Just watch out, sometimes the +10's can be too strong. I had an issue last year at Florida Open because the springs were brand new and one of them wouldn't let the gun go into battery. Link to comment Share on other sites More sharing options...
digi Posted January 5, 2014 Share Posted January 5, 2014 Yup same problem here with the stock springs. Replaced the one with the +10% and fixed it. Then another mag had the same issue. Ended up swapping them all over and never had a problem since. Link to comment Share on other sites More sharing options...
RNA Posted January 5, 2014 Share Posted January 5, 2014 Do the weak mag springs occur in only full size cz magazines? Are these weaker springs also in the mec gar compact magazines? What about the mec gar full size? Link to comment Share on other sites More sharing options...
chuck s Posted January 5, 2014 Author Share Posted January 5, 2014 I will get the plus springs when my new mags come in, in the mean time I will check out the m&p springs and let you know how they are working out. Thanks guys Link to comment Share on other sites More sharing options...
mgardner Posted January 5, 2014 Share Posted January 5, 2014 I usually run the 19 round MegGar magazines without issue. Same thing happened last week to me on a slide lock reload when an old CZ mag got into the mix. Cost me 5 seconds clearing the gun. Needless to say I got hammered.

Be careful shooting a major with those 19 round MecGar's. I've personally witnessed a shooter getting the bump to open at a level 2 when the gun wouldn't fit in the box. Those mags are slightly bigger than the CZ originals. Just big enough to make the gun not fit. Link to comment Share on other sites More sharing options...
mgardner Posted January 5, 2014 Share Posted January 5, 2014 I've never shot this gun at a major match in Production and you're right it won't fit. I have shot it in Limited. Thanks for the heads up. I have a 97B that I have been shooting in Production. I just got this gun back from loaning it and shot 1 match in Production so far. Guess I got lucky. :-) Link to comment Share on other sites More sharing options...
asimonp79 Posted January 5, 2014 Share Posted January 5, 2014 What I suggest is as follows: About the springs - just for you to know that the +10% springs are a good thing , but they are not production legal ( I seen a tread on IPSC global Village) Have your 4 mags for training and 4 mags for competition. Mark the Mags 1 2 3 4 Make sure that competition mag that you drop FIRST will be number 4. That how you know that it is the "most working mag". Now after a while the mag N4 will make trouble- put it with the " training mags" Regards, Link to comment Share on other sites More sharing options...
