I have read contrasting reports on the compatibility of 9mm CZ-75B magazines with the IWI Jericho 941 9mm steel frame. I have a bunch of 75B mecgar factory mags and really want that Jericho now that it has a discrete rail and frame mounted safety.  I'm only interested in the new IWI Jericho because I already have a 76B. This is going to be a bed-side gun.

I found this from a board saying they're NOT compatible:

"CZ75 magazine and clone compatibility chart

1. Pre-series 88 frame Tanfoglio/FIE/EXCAM (TA90) pistols CAN use CZ75 magazines and vise versa.

2. CZ97B uses the same magazines as the full-size .45 Witness. They are not identical to Tanfoglio OEM magazines, but they fit and function.

3. Jericho 941, Baby Eagle, Tanfoglio TZ75 Series 88 and later, FIE/EXCAM TA90, and Springfield P9 all Interchange .

4. Baby Eagle mags WORK in CZ-85 Combats and in 75Bs, but will NOT work in a pre-B CZ75.

5. CZ75 factory 15 round mags (9mm) fit in Sphinx AT2000 Police Specials, but CZ mags do NOT lock the slide open.

6. Action Arms AT-84 magazines WORK in Pre-B CZ75’s, but NOT vice versa. CZ75 Mec-Gar(16 rd) magazines WORK in the AT-84. Tanfoglio magazines Work in the AT-84.

7. Israeli (IMI) made CZ75 magazines WORK in pre-series 88 TZ75’s

8. CZ75 factory 9mm 10/15 rd mags will NOT work in an Baby Eagle, NOR will CZ75B .40 mags work in a Baby Eagle .40

9. The Tanfoglio 18 rd 9mm magazines made for the Large Frame .45/10mm/.38 Super Witness pistols will NOT fit Small frame Witness/Baby Eagle pistols.

10. BTA 90 88 series WORKS with Mec-Gar compact Witness/Baby Eagle magazines.

11. CZ SP01 19 rd mags Work in Jericho 941/Baby Eagles."

Anyone have some wisdom to share?

The CZ75B mags I had would work fine in terms of feeding in a baby DE, but they would not reliably activate the slide lock.

I have some of the Elander mags that are marked Jericho,Tanfoglio, BE, CZ-95. They ran fine in the wife's poylmer BDE, but for some reason if you did a DA pull, it didn't want to ignite the primer on occasion. I have no idea why. I switched back to the factory BDE mags, and gun went back to functioning 100%

Thanks for the reply guys.

Most of the problems I am finding is with the base pads on some magazines and of course the follower in the mag. are the main problems. I have a 17 round flat/metal based Mec Gar magazine on order and should be ok.

Has anyone tried this mag

Small frame witness magazine

Kind of worried that the base pad might keep it from seating.

I got the magazine in and all is well. No problems with it. It seats in perfectly and locks the slide back.

This thread feels like time travel but...

I have an IWI Jericho full-size, steel frame.

A factory CZ-75b mag ran fine but was finicky on last round slide lock. I believe the mag was just a hair too short to allow the follower to activate the slide lock 100% of the time.

However, a MEC-GAR CZ-75b 19 round magazine fits and functions PERFECTLY!

OOS @ PSA but available from Brownells and other places

MEC-GAR CZ-75b 19 round magazine

Thanks Makarov,

I'll give those a try.

Got these in and with hand cycling they lock the slide. They are also BEAUTIFUL!

***UPDATE***
These worked perfectly. Thanks for the heads up. I like the blue followers, too.

Compatability #11 yes they do.
For some reason the 19rd mags fit better.
