Mags drop / don't drop

[DWARREN]

When you checked the mag dimensions were the mags loaded or empty, makes a difference.

The larger capacity Mecgars can be "different."

I bought several for my CZ 85 (Pre B) and my son's CZ75SAO.

I'd used 16 round magazines to test my fitting work to allow me to use modern magazines in my Pre B pistol's frame.  No time at all I had them sliding in and dropping out.

So, I went three better (19 round Mecgars).  I kept 8, have my youngest so the rest.  Loaded them up, set some aside for the CZ75 Compacts and four for the Pre B CZ85.  One day I ran into a 19 round magazine that wouldn't fully insert into the Pre B pistol.  Then I had to check all of them.  Of the eight 19 round magazines, only four would insert smoothly.  I emptied the ammo from them and talked to my youngest son.  He tried the in his CZ75 SAO and all four worked great.  I tried the first batch I'd bought for him and ran across four that would insert smoothly/completely into the Pre B CZ85.  All of them are Mecgar 19 round magazines.  Some worked in the Pre B (with the frame/mag. well filed to open it up for modern magazines) and some didn't.

I also removed the magazine brake from the Pre B CZ85 way back there.  It was sort of bent/twisted and binding even with the 16 round mgazines, so I removed it and never looked back.  Now I can see, and lube, the hammer spring and strut any time I have the magazine out.

My issue was the mag release button was traveling too far into the mag well under match conditions. During dry fire practice or simple range time I was pushing but no so far that it was touching the mags on the thumb side. During a match the adrenaline and pressure of the competition had me pushing hard to ensure a clean reload, but I pushed so hard that the inside of the release itself was contacting the mag and holding it in place.

The video that was posted above was the solution i used. Works great now. The button now rattles a bit when no mag is in it. Its fine with a mag. Super clean reloads now.

Adjust the mag brake. Bend it so it doesn’t make that much of a bow flatten it out.  That’s the issue.

Thanks for all the discussion - plenty to learn when you get a new brand of gun !

I'll post a follow up when I get everything sorted.  Sounds like I may finally get some range time tonight; looking forward to dialing this one in.
