Jericho 941 9mm magazines

I tried the CZ route and did not have good results. The magazines needed to be slammed into the gun to seat properly, though it would have been an easy enough fix to file a little off the topside of the base-plate's lip. I managed to straight trade the two CZ mags for two Jericho mags. YMMV.
 
They are so close that I know that the swap works one way but not quite the other. Blastattack's post makes it think that it's the 941 mag works OK in the CZ but not the other way. It's a really small thing though. The magazine notch for the catch would not quite lock. That's why Blastattack's post makes me think it's a case of the CZ mag needing to be very slightly modified.

It's so close that if you hold the mag hard into the well with one hand that the 941 will strip and shoot the ammo just fine. It just doesn't lock in place... usually.

I was there when a couple of guys did this back and forth thing with the CZ and Jericho mags in their guns because they too were curious. When laid side by side the notches were just barely out of place. It looked like a business card thickness worth of metal removed would allow it to lock into the gun and mag setup with the poor match.

CZ's are so common that it shouldn't be hard to find someone that will let you try one of their mags to see if this works. And even to the point of duplicating that test those two did of holding the mag firmly in position while shooting the gun to ensure it feeds without jamming and that the empty drops clear. It did in their case but it's always nicer to be personally sure of it.

But at $40 to $45 that I've seen the CZ mags selling for I'm not sure it's a cost savings.

That could be it too, I never really looked at the catch cut-out and compared them. However, once seated the CZ mags worked without issue, but they took an unnecessarily great amount of force to seat. The Jericho mags in the Jericho are somewhat loose, whereas the CZ mags in the Jericho were slammed hard up against the bottom of the frame. I suspect that relieving the base-plate on of the CZ mags would make them work better, but I wasn't in a position to ruin a $50 mag for the sake of experimentation. Make note that only new CZ magazines work. Older "pre-B" do not work at all.
