ultimase Posted April 28, 2015 Share Posted April 28, 2015 Looking to replace some 10 round mag springs for mags that came with my cz75b years ago. Checked with czc and they are listed as out of stock online, cgw doesn't carry them and wolff doesn't carry them for 10 rounders either. Anyone know of any sources for the 10 round mag springs?

himurax13 Posted April 28, 2015 Share Posted April 28, 2015 Well if CZ USA or Wolff doesn't have them, you are out of luck. On the other hand, Greg Cote LLC sells 10 round CZ75 Mecgar mags for $21. Link to comment Share on other sites More sharing options...
brian45acp Posted May 4, 2015 Share Posted May 4, 2015 I just did this. Get the 5% extra power springs from CZ custom shop. There is no separate spring for the 10 rounders they are the same for the full capacity mags. I just ran the 5% springs this saturday and had no issues and my mags were less sensitive to dirt/sand in them compared to the stock springs.

The 10 round mags with the plastic bottom pieces have shorter bodies. I would imagine that there would be less coils on the shorter mags. Link to comment Share on other sites More sharing options...
ultimase Posted May 5, 2015 Author Share Posted May 5, 2015 I've noticed the difference between the full cap and the 10 rounders as well, but there does seem to be an agreement in some other forums that the full cap springs do work with the 10 rounders.

brian45acp Posted May 25, 2015 Share Posted May 25, 2015 I been running the 5% extra power springs paste few matches and love them. I havent taken my mags apart since the switch. I just knock out any dirt/sand and wipe the mags off best I can. Before the switch it was like the mag springs would go dead despite being new mags when just the smallest amount of dirt got in them. The full length springs work great. CZ does the same thing was my understanding. Meaning they use the full capacity mag springs in the 10 rounder mags which in theory should make the springs extra power. All I know is the 5% springs for the full capacity mags is the sweat spot for us 10 rounder users. For my Rami I have no idea what to use so I think its going to have to stay stock springs. I havent seen an extra power sub compact spring yet. Link to comment Share on other sites More sharing options...

These are mags I am referring to that might give you problems finding replacements for. http://czcustom.com/CZ-75-CZ-85-9mm-10-Round.aspx The other styles that have a full length body should use the regular ones for the standard capacity magazines.

brian45acp Posted May 30, 2015 Share Posted May 30, 2015 Those are the mags I have. http://czcustom.com/CZ75magazinesprings5.aspx These are the springs I have been using and I love them. I did have to take a flat head screw driver and open up the retaining plate a little. Our retaining plates dont look anything like the regular ones for the high cap mags. Ours sort of hook on to the spring coil vs having that eyelet that you thread the spring onto. I havent taken my mags apart now in 4 matches and no failures to speak of. I did leave the mags loaded full over night the night before I first used them. Link to comment Share on other sites More sharing options...
Czman Posted June 1, 2015 Share Posted June 1, 2015 I just installed Wolff +5% springs - wow, very nice on my 10 rd TS / CM mag with Springer base. Link to comment Share on other sites More sharing options...
CeeZer Posted June 1, 2015 Share Posted June 1, 2015 I used +10% springs in my 10rd mags, only thing is - tough to load last couple of rounds but I use UpLula ever since I cut my 'loading' thumb at work just before a match Link to comment Share on other sites More sharing options...
ultimase Posted June 29, 2015 Author Share Posted June 29, 2015 Picked up the springs from czc and ran a match over the weekend. One mag rattled slightly the other was solid. Both ran without any issues. Link to comment Share on other sites More sharing options...
brian45acp Posted June 29, 2015 Share Posted June 29, 2015 All my mags rattle. Springs aren't going to change that and just like my 1911s it doesn't affect anything. It does tell the informed around me I have concealed a gun on though, lol. Link to comment Share on other sites More sharing options...
ultimase Posted June 30, 2015 Author Share Posted June 30, 2015 Weirdly it started rattling on the 9th round, it sounds like one of the rounds isn't under tension and it's hitting the mag body. Link to comment Share on other sites More sharing options...
